Service Precautions for 4WD Model

This 4WD model does not have the feature that mechanically switches between 4WD (four-wheel drive) and 2WD (front-wheel drive).

Do not drive the vehicle with rear wheels on the ground even though the front wheels are off the ground. The front wheel power is conveyed to the rear wheels, and the vehicle will start off.

Always lift the vehicle up so all four wheels are off the ground when testing and inspecting the vehicle to rotate the wheels such as Pressure Tests.

Use the free rollers under the rear wheels when performing test the vehicle with the speedometer tester.

Precautions on using free rollers:

  • Inspecting and testing using a chassis dynamometer is not feasible.
  • Do not operate the accelerator, brake pedal or steering wheel abruptly. It may cause the vehicle to roll and create a hazardous condition.
  • The maximum testing speed should be 50 km/h (31 mph).
  • The maximum continuous operating time should be 3 minutes.
  • Make sure to tie down the vehicle securely with the side anchor wires and center tie down wire. The free rollers are to be set under the rear wheels.

    CAUTION

  • Make sure to place the free rollers parallel to the roller of each speedometer tester.
  • Putting the front and rear wheels on the speedometer testers and free rollers inappropriately may cause the vehicle to roll off or over the free rollers and create a hazardous condition.
  • The side anchor wires and certain tie-down wire must be appropriately tensioned. If the wires have too much slack, the expected tie-down efficiency cannot be obtained.
  • When attaching the side anchor wires and center tie-down wire, make sure they are not interfering with the bumper and other parts of the vehicle body.
  • Do not attach the wires to any place other than the designed areas.
  • Do not operate the speedometer testers at a speed more than 50 km/h (31 mph) or for more than 3 minutes.


    1. Set the free rollers according to the wheel base and tread of the vehicle.
    2. Move the vehicle to position the front wheels on the speedometer tester and the rear wheels on the free rollers. Make sure to align the center of the wheels to the center of the speedometer tester and the free rollers.
    3. Tie down the vehicle securely using the towing hook and tie-down hook bracket to prevent the vehicle from rolling or over the free rollers.
    4. Start the engine, shift the transmission into the [D] position, accelerate the vehicle gradually, and measure the vehicle speed.
    5. After measurement, use the brake pedal to gradually decelerate and stop the vehicle.

    General Troubleshooting Information14-4

    How to Check for DTCs with the PGM Tester/Scan Tool

    When the Powertrain Control Module (PCM) senses an abnormality in the input or output systems, the [D] indicator (A) in the gauge assembly (B) will usually blink.


    When the 16P Data Link Connector (DLC) (A) (located under the dash behind the center console) is connected to the OBD Scan Tool or Honda PGM Tester (B), it will indicate the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (II).

    NOTE: The illustration shows LHD model; RHD is symmetrical.


    If the [D] indicator or MIL has been reported on, or if a driveability problem is suspected, follow this procedure:

    1. Connect the OBD Scan Tool or Honda PGM Tester to the DLC. (See the OBD Scan Tool or Honda PGM Tester user's manual for specific instructions. If you are using the Honda PGM Tester, make sure it is set to the SAE DTC type).
    2. Turn the ignition switch ON (II), and observe the DTC on the screen.
    3. Record all fuel and emissions DTCs, A/T DTCs, and freeze data.
    4. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC except for DTC P0700. DTC P0700 means there is one or more A/T DTCs, and no problems were detected in the fuel and emissions circuit of the PCM.
    5. Reset the DTC stored in the PCM with the OBD Scan Tool or PGM Tester.
    6. Drive the vehicle for several minutes under the same conditions as those indicated by the freeze data, or at speeds over 30 mph (50 km/h), and then recheck for DTC(s). If the A/T DTC returns, go to the DTC Troubleshooting Index. If the DTC does not return, there was an intermittent problem within the circuit. Make sure all pins and terminals in the circuit are tight.
    7. Reset the radio preset stations, and set the clock.

    NOTE: You can also check for DTCs with SCS signal terminals short-circuited using with the special tool (DLC pin box 07WAJ-0010100) (see section Appendix).

    14-5

    How to Troubleshoot Circuits at the PCM

    1. Remove the glove box stops, then bring the glove box down.
    2. Loosen the mounting nut (A) on the lower portion of the PCM (B), and remove the mounting bolt (C) and nut (D).
    3. NOTE: The illustration shows LHD model; RHD is symmetrical.


    4. Lift the PCM up to clear the mounting nut on the lower portion of the PCM, then pull out the PCM.
    5. Inspect the circuit on the PCM, according to the DTC troubleshooting with a digital multitester (A) and tapered tip probe (B) as shown.


    6. If you cannot get to the wire side of the connector or the wire side is sealed, disconnect the connector and use the tester probe to probe the connectors from the terminal side. Do not force the probe into the connector.

    General Troubleshooting Information (cont'd)14-6

    PCM Reset Procedure

    1. Write down the radio station presets.
    2. Turn the ignition switch OFF.
    3. Remove the No. 6 ECU fuse (15A) (A) from the under-hood fuse/relay box (B) for more than 10 seconds.


    How to End a Troubleshooting Session

    This procedure must be done after any troubleshooting.

    1. Turn the ignition switch OFF.
    2. Disconnect the Honda PGM tester (A) from the DLC (B).
    3. NOTE: The illustration shows LHD model; RHD is symmetrical.


    4. Reset the PCM.
    5. Turn the ignition switch ON (II).
    6. To verify that the problem is repaired, test-drive the vehicle for several minutes at speeds over 30 mph (50 km/h).

    Notes

    Engine runs, but vehicle does not move in any gear
  • Low ATF level
  • Shift cable broken or out of adjustment
  • Joint in shift cable and transmission or body worn
  • ATF pump worn or binding
  • Regulator valve stuck or spring worn
  • ATF strainer clogged
  • Mainshaft worn or damaged
  • Final gears worn or damaged
  • Transmission-to-engine assembly error
  • Axle disengaged
  • Check ATF level and check ATF cooler lines for leakage and loose connections. If necessary, flush ATF cooler lines.
  • Check for loose shift cable on the shift lever and the transmission control shaft.
  • Improper alignment of ATF pump and torque converter housing may cause ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak.
  • Measure line pressure.
  • Be careful not to damage the torque converter housing when replacing the main ball bearing. You may also damage the ATF pump when you torque down the main valve body. This will result in ATF pump seizure if not detected. Use the proper tools.
  • Install the main seal flush with the torque converter housing. If you push it into the torque converter housing until it bottoms out, it will block the fluid return passage and result in damage.
  • Check the ATF strainer for clogged. If the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump. If the ATF pump is OK, find the damaged components that caused debris, and no cause for contamination is found, replace the torque converter.
  • Inspect the differential pinion shaft for wear under the pinion gears. If the differential pinion shaft is worn, overhaul the differential assembly, replace the ATF strainer, thoroughly clean the transmission, and flush the torque converter, cooler, and lines.
  • Vehicle moves in [2] or [R], but not in [D] or [1] position
  • 1st accumulator defective
  • 1st gears worn or damaged
  • 1st clutch defective
  • Check the 1st clutch pressure.
  • Inspect the clutch piston and O-rings. Check the spring retainer and retainer seal for wear and damage. Inspect the clutch end plate-to-top disc clearance. If the clearance is out of tolerance, inspect the clutch discs and plates for wear and damage. If the discs are worn or damaged, replace them as a set. Inspect clutch waved-plate phase difference. If the phase difference is out of tolerance, replace the waved-plate. If they are OK, adjust the clearance with the clutch and plate.
  • Inspect the 1st clutch feed pipe. If the 1st clutch feed pipe is scored, replace it and O-ring under the feed pipe guide.
  • Replace the secondary shaft if the bushing for the 1st clutch feed pipe is loose or damaged.

    System Description14-19

    General Operation

    The automatic transmission is a combination of a 3-element torque converter and triple-shaft electronically controlled unit which provides 4 speeds forward and 1 reverse. The entire unit is positioned in line with the engine.

    Torque Converter, Gears, and Clutches

    The torque converter consists of a pump, turbine, and stator assembly in a single unit. They are connected to the engine crankshaft so they turn together as the engine turns. Around the outside of the torque converter is a ring gear which meshes with the starter pinion when the engine is being started. The entire torque converter assembly serves as flywheel while transmitting power to the transmission mainshaft, the transmission has three parallel shafts; the mainshaft, the countershaft, the secondary shaft. The mainshaft is in line with the engine crankshaft, and includes the 3rd and 4th clutches, and gears for 3rd, 4th, reverse, and idler. The mainshaft reverse gear is integral with the mainshaft 4th gear. The countershaft includes the gears for 1st, 2nd, 3rd, 4th, reverse, park, and the final drive. The final drive gear is integral with the countershaft. The countershaft 4th gear and the countershaft reverse gear can be locked to the countershaft providing the 4th or reverse gear, depending on which way the selector is moved. The secondary shaft includes the 1st and 2nd clutches, and gears for 1st, 2nd, and idler. The idler shaft is located between the mainshaft and secondary shaft, and the idler gear transmits power between the mainshaft and the secondary shaft. The gears on the mainshaft and the secondary shaft are in constant mesh with those on the countershaft. When certain combinations of gears in the transmission are engaged by the clutches, power is transmitted from the mainshaft and the secondary shaft to the countershaft provide [D], [2], [1], and [R] positions.

    Electronic Control

    The electronic control system consists of the Powertrain Control Module (PCM), sensors, and solenoid valves. Shifting and lock-up are electronically controlled for comfortable driving under all conditions. The PCM is located below the dashboard, behind the glove box.

    Hydraulic Control

    The valve bodies include the main valve body, the regulator valve body, and the servo body. They are bolted to the torque converter housing. The main valve body contains the manual valve, the shift valves A, B, C, and E, the relief valve, the lock-up control valve, the cooler check valve, the servo control valve, and the ATF pump gears. The regulator valve body contains the regulator valve, the torque converter check valve, lock-up shift valve, and the 1st accumulator. The servo body contains the servo valve, the CPB valve, accumulators for 2nd, 3rd and 4th and shift solenoid valves for A, B, C, and E. Fluid from the regulator passed through the manual valve to the various control valves. The 1st and 3rd clutches receive fluid their respective feed pipes, and the 2nd and the 4th clutches receive fluid from the internal hydraulic circuit.

    Shift Control Mechanism

    The PCM controls to shift gears the shift solenoid valves A, B, C, and E, and the A/T clutch pressure control solenoid valves A, B, and C, while receiving input signals from various sensors and switches located throughout the vehicle. The shift solenoid valves shift the positions of the shift valves to switch the port leading hydraulic pressure to the clutch. The A/T clutch pressure control solenoid valves A, B, and C regulate their respective pressure, and pressurize to the clutches to engage it and its corresponding gear. The pressures of the A/T clutch pressure control solenoid valves also apply to the shift valves to switch the port.

    Lock-up Mechanism

    The lock-up mechanism operates in [D] position (3rd and 4th) and [D] position over-drive off mode (3rd). The pressurized fluid is drained from the back of the torque converter through a fluid passage, causing the torque converter clutch piston to be held against the torque converter cover. As this takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together with the hydraulic control, the PCM optimizes the timing and volume of the lock-up mechanism. When the shift solenoid valve E is turned on by the PCM, shift solenoid valve E pressure switch the lock-up shift valve lock-up on and off. The A/T clutch pressure control solenoid valve A and the lock-up control valve control the volume of the lock-up conditions.

    Automatic Transaxle (A/T) Gear Position Indicator

    The A/T gear position indicator in the instrument panel shows which position has been selected.

    Transfer Mechanism (4WD)

    The transfer mechanism consists of the transfer drive gear on the differential, the transfer shaft, the transfer drive gear (hypoid gear), the transfer driven gear shaft (hypoid gear), and the companion flange. The transfer mechanism assembly is on the rear of the transmission, beside the differential. The transfer drive gear on the differential drives the transfer gear shaft and transfer driven gear (hypoid gear), and the transfer drive gear (hypoid gear) drives the transfer driven gear shaft (hypoid gear). Power is transmitted from the transfer drive gear on the differential to the rear differential via the transfer and the propeller shaft.

    System Description (cont'd)14-22

    Clutches

    The 4-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears. When hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs and steel plates together, locking them so they don't slip. Power is then transmitted through the engaged clutch pack to its hub-mounted gear. Likewise, when the hydraulic pressure is bled from the clutch pack, the piston releases the friction discs and steel plates, and they are free to slide past each other. This allows the gear to spin independently on its shaft, transmitting no power.

    1st Clutch

    The 1st clutch engages/disengages 1st gear, and is located at the middle of the secondary shaft. The 1st clutch is supplied hydraulic pressure by its ATF feed pipe within the secondary shaft.

    2nd Clutch

    The 2nd clutch engages/disengages 2nd gear, and is located at the end of the secondary shaft, opposite the end cover. The 2nd clutch is supplied hydraulic pressure by a circuit connected to the internal hydraulic circuit.

    3rd Clutch

    The 3rd clutch engages/disengages 3rd gear, and is located at the middle of the mainshaft. The 3rd clutch is joined back-to-back to the 4th clutch. The 3rd clutch is supplied hydraulic pressure by its ATF feed pipe within the mainshaft.

    4th Clutch

    The 4th clutch engasges/disengages 4th gear, as well as reverse gear, and is located at the middle of the mainshaft. The 4th clutch is joined back-to-back to the 3rd clutch. The 4th clutch is supplied hydraulic pressure by a circuit connected to the internal hydraulic circuit.

    Gear operation

    Gears on the mainshaft:

  • The 4th gear is engages/disengages with the mainshaft by the 4th clutch.
  • The 3rd gear is engages/disengages with the mainshaft by the 3rd clutch.
  • The reverse gear is engages/disengages with the mainshaft by the 4th clutch.
  • The idler gear is splined with the mainshaft, and rotates with the mainshaft.
  • Gears on the countershaft:

  • The final drive gear is integral with the countershaft.
  • The 1st, 2nd, 3rd, and park gears are splined with the countershaft, and rotates with the countershaft.
  • The 4th gear and reverse gear are rotate freely from the countershaft. The reverse selector engages 4th gear and reverse gear with the reverse selector hub. The reverse selector hub is splined to the countershaft so that the 4th gear and reverse gear engage with the countershaft.
  • Gears on the secondary shaft:

  • The 1st gear is engaged/disengages with the secondary shaft by the 1st clutch.
  • The 2nd gear is engaged/disengages with the secondary shaft by the 2nd clutch.
  • The idler gear is splined with the secondary shaft, and rotates with the secondary shaft.
  • The idler gear on the idler shaft transmits power between the mainshaft and the secondary shaft.

    The reverse idler gear transmits power from the mainshaft reverse gear to the countershaft reverse gear, and changes rotation direction of the countershaft to reverse.

    14-23

    [P] Position

    Hydraulic pressure is not applied to the clutches. Power is not transmitted to the countershaft. The countershaft is locked by the park pawl interlocking the park gear.

    [N] Position

    Engine power transmitted from the torque converter drives the mainshaft idler gear, the idler shaft idler gear, and the secondary shaft idler gear, but hydraulic pressure is not applied to the clutches. Power is not transmitted to the countershaft. In this position, the position of the reverse selector differs according to whether the shift lever shifted from [D] or [R] position:

  • When shifted from [D] position, the reverse selector engages with the countershaft 4th gear and the reverse selector hub, and the 4th gear engages with the countershaft.
  • When shifted from [R] position, the reverse selector engages with the countershaft reverse gear and the reverse selector hub, and the reverse gear engages with the countershaft.

    Electronic Control System

    Functional Diagram

    The electronic control system consists of the Powertrain Control Module (PCM), sensors, and solenoid valves.

    Shifting and lock-up are electronically controlled for comfortable driving under all conditions.

    The PCM inputs signals from the sensors, switches, and other control units, perform processing data, and outputs signals for engine control system and A/T control system. The A/T control system includes shift control, grade logic control, clutch pressure control, and lock-up control is stored in the PCM.

    The PCM switches the shift solenoid valves and the A/T clutch pressure control solenoid valves on hydraulic control to control shifting transmission gears and lock-up torque converter clutch.

    NOTE: The illustrations shows LHD model; RHD model is similar.



    14-31

    Shift Control

    The PCM instantly determines which gear should be selected by various signals sent from sensors and switches, and it actuates the shift solenoid valves A, B, C, and E to control shifting.

    Also, a Grade Logic Control System has been adopted to control shifting in [D] position. The PCM compares actual driving conditions with memorized driving conditions, based on the input from the throttle position sensor, the engine coolant temperature sensor, the barometric pressure sensor, the brake pedal position switch signal, and the shift lever position signal, to control shifting while vehicle is ascending or descending a slope.


    System Description (cont'd)14-32

    The PCM turns the shift solenoid valves A, B, C, and E ON and OFF to control shifting transmission gear. The combination of driving signals to shift solenoid valves A, B, C, and E are shown in table below.

    When the PCM determines that the vehicle is climbing a hill in [D] position, the system extends the engagement area of 2nd, and 3rd gears to prevent the transmission from frequently shifting between 2nd and 3rd gears, and between 3rd and 4th gears, so the vehicle can run smooth and have more power when needed.

    Shift schedules stored in the PCM between 2nd and 3rd gears, and between 3rd and 4th gears, enable it to automatically select the most suitable gear according to the magnitude of a gradient.


    Descending Control

    When the PCM determines that the vehicle is going down a hill in [D] position, the shift-up speed from 3rd to 4th gear, and from 2nd to 3rd gear (when the throttle is closed) becomes faster than the set speed for flat road driving to widen the 3rd gear and 2nd gear driving area. This, in combination with engine braking from the deceleration lock-up, achieves smooth driving when the vehicle is descending. There are three descending modes with different 3rd gear driving areas, and 2nd gear driving areas according to the magnitude of a gradient stored in the PCM. When the vehicle is 4th gear, and you are decelerating when you are applying the brakes on a steep hill, the transmission will downshift to lower gear. When you accelerate, the transmission will then return to higher gear.

    Clutch Pressure Control

    The PCM actuates the A/T clutch pressure control solenoid valves A, B and C to control the clutch pressure. When shifting between lower and higher gears, the clutch pressure regulated by the A/T clutch pressure control solenoid valves A, B, and C engage and disengage the clutch smoothly.

    The PCM inputs signals from the various sensors and switches, perform processing data, and outputs a current to the A/T clutch pressure control solenoid valves A, B, and C.


    14-35

    Lock-up Control

    The shift solenoid valve E controls the hydraulic pressure to switch the lock-up shift valve and lock-up ON and OFF.

    The PCM actuates the shift solenoid valve E and the A/T clutch pressure control solenoid valve A to control the torque converter clutch lock-up. When the shift solenoid valve E is turned ON, the condition of the lock-up starts.

    The A/T clutch pressure control solenoid valve A regulates and apply the hydraulic pressure to the lock-up control valve to control the volume of the lock-up.

    The lock-up mechanism operates in 3rd and 4th gears in [D] position, and 3rd gear in [D] position over-drive off mode.

    Hydraulic Controls

    The valve body includes the main valve body, the regulator valve body, and the servo body. The ATF pump is driven by splines on the left end of the torque converter which is attached to the engine. Fluid flows through the regulator valve to maintain specified pressure through the main valve body to the manual valve, directing pressure to the shift valves and to each of the clutches via the solenoid valves. The shift solenoid valves A, B, C, and E are bolted on the servo body. The A/T clutch pressure control solenoid valves A, B, and C are mounted on the outside of the transmission housing.


    System Description (cont'd)14-42

    Main Valve Body

    The main valve body contains the manual valve, the shift valves A, B, C, and E, the relief valve, the lock-up control valve, the cooler check valve, the servo control valve, and the ATF pump gears. The primary function of the main valve body is to switch fluid pressure on and off and to control hydraulic pressure going to the hydraulic control system.


    Regulator Valve Body

    The regulator valve body contains the regulator valve, the torque converter check valve, lock-up shift valve, and the 1st accumulator.


    14-43

    Regulator Valve

    The regulator valve maintains a constant hydraulic pressure from the ATF pump to the hydraulic control system, while also furnishing fluid to the lubrication system and torque converter. The fluid from the ATF pump flows through B and B'. Fluid entering from B flows through the valve orifice to the A cavity. This pressure of the A cavity pushes the regulator valve to the right side, and this movement of the regulator valve uncovers the fluid port to the torque converter and the relief valve. The fluid flows out to the torque converter and the relief valve, and the regulator valve moves to the left side. According to the level of the hydraulic pressure through B, the position of the regulator valve changes, and the amount of fluid from B' through torque converter also changes. This operation is continued, maintaining the line pressure.

    NOTE: When used, ''left'' or ''right'' indicates direction on the illustration below.


    Increases in hydraulic pressure according to torque are performed by the regulator valve using stator torque reaction. The stator shaft is splined with the stator in the torque converter, and its arm end contacts the regulator spring cap. When the vehicle is accelerating or climbing (Torque Converter Range), stator torque reaction acts on the stator shaft, and the stator arm pushes the regulator spring cap in the direction of the arrow in proportion to the reaction. The stator reaction spring compresses, and the regulator valve moves to increase the line pressure which is regulated by the regulator valve. The line pressure reaches its maximum when the stator torque reaction reaches its maximum.


    System Description (cont'd)14-44

    Servo Body

    The servo body contains the servo valve, the clutch pressure back-up (CPB) valve, accumulators for 2nd, 3rd, and 4th, and shift solenoid valves for A, B, C, and E.


    Accumulator

    The accumulators are located in the regulator valve body and the servo body. The regulator valve body contains the 1st accumulator, and the servo body contains the 2nd, 3rd, and 4th accumulators.


    14-45

    Hydraulic Flow

    Distribution of Hydraulic Pressure

    As the engine turns, the ATF pump starts to operate. Automatic transmission fluid (ATF) is drawn through the ATF strainer (filter) and discharged into the hydraulic circuit. Then, ATF flowing from the ATF pump becomes line pressure that's regulated by the regulator valve. Torque converter pressure from the regulator valve enters the torque converter through the lock-up shift valve, and it is discharged from the torque converter. The torque converter check valve prevents torque converter pressure from rising.

    The PCM controls the shift solenoid valves ON and OFF. The shift valve intercepts line pressure from the ATF pump via the manual valve when the shift solenoid valve is OFF. When the shift solenoid valve is turned ON, line pressure changes to shift solenoid valve pressure at the shift solenoid valve, then the solenoid valve pressure flows to the shift valve. Applying shift solenoid pressure to the shift valves moves the position of the shift valve, and switches the port of the hydraulic circuit. The PCM also controls A/T clutch pressure control solenoid valves A, B, and C. The A/T clutch pressure control solenoid valves regulate hydraulic pressure, and apply the pressure to the clutches for engaging smoothly. The clutches are received optimum clutch pressure which is regulated by the A/T clutch pressure control solenoid valves for comfortable driving and shifting under all conditions.

    Hydraulic pressure at the port is as follows:

    [R] Position: Shifting to [R] position from [P] or [N] position

    When shifting in [R] position, the PCM turns shift solenoid valves B and E ON, A and C OFF. Shift solenoid valve B pressure (SB) is applied to the right side of the shift valve B, and the shift valve B is moved to left side. Shift solenoid valve E pressure (SE) is applied to the left side of the shift valve E, and the shift valve E is moved to the right side. Line pressure (1) changes to (3) at the manual valve, and flows to the servo valve via the shift valve E. The servo valve is moved to reverse range position. Movement of the shift valves B and E, and servo valve creates 4th clutch pressure line between the 4th clutch and the A/T clutch pressure control solenoid valve A. The 4th clutch pressure (40) is applied to the 4th clutch, and the 4th clutch is engaged gently.

    NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.


    System Description (cont'd)14-58

    [R] Position: Driving in reverse gear

    After starting off in reverse gear, the PCM turns shift solenoid valves A ON, and remains B and E ON, C OFF. Shift solenoid valve A pressure (SA) is applied to the right side of the shift valve A to cover the port of A/T clutch pressure control solenoid valve A pressure, and to uncover the port of line pressure leading to the 4th clutch creating full line pressure. The 4th clutch is engaged securely with line pressure.

    Reverse Inhibitor Control

    While the vehicle is moving forward, the PCM controls shift solenoid valve E remaining OFF. The shift valve E covers the port of line pressure (3') leading to the servo valve reverse position. The servo valve cannot be shifted to reverse position, and hydraulic pressure is not applied to the 4th clutch from servo valve for reverse, as a result, power is not transmitted to the reverse direction.

    NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.


    14-59

    [P] Position

    Shift solenoid valves B and E are turned ON, and A, and C OFF by the PCM. Line pressure (1) flows to the shift solenoid valves and the A/T clutch pressure control solenoid valve A. Line pressure (3) changes to (3') at the shift valve E, and flows to the servo valve. The servo valve is moved to reverse/park position. Hydraulic pressure is not applied to the clutches.


    System Description (cont'd)14-60

    Lock-up System

    The lock-up mechanism of the torque converter clutch operates in [D] position (3rd and 4th) and [D] position over-drive off mode (3rd). The pressurized fluid is drained from the back of the torque converter through a fluid passage, causing the torque converter clutch piston to be held against the torque converter cover. As this takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together with the hydraulic control, the PCM optimizes the timing and volume of the lock-up mechanism. When the shift solenoid valve E is turned on by the PCM, shift solenoid valve E pressure switch the lock-up shift valve lock-up on and off. The A/T clutch pressure control solenoid valve A and the lock-up control valve control the volume of the lock-up conditions.

    Torque Converter Clutch Lock-up ON (Engaging Torque Converter Clutch)

    Fluid in the chamber between the torque converter cover and the torque converter clutch piston is drained off, and fluid entered from the chamber between the pump and stator exerts pressure through the torque converter clutch piston against the torque converter cover. The torque converter clutch piston engages with the torque converter cover; torque converter clutch lock-up ON, and the mainshaft rotates at the same as the engine.


    Torque Converter Clutch Lock-up OFF (Disengaging Torque Converter Clutch)

    Fluid entered from the chamber between the torque converter cover and the torque converter clutch piston passes through the torque converter and goes out from the chambers between the turbine and the stator, and between the pump and the stator. As a result, the torque converter clutch piston moves away from the torque converter, and the torque converter clutch lock-up is released; torque converter clutch lock-up OFF.


    14-61

    No Lock-up

    Shift solenoid valve E is turned OFF by the PCM, and shift solenoid valve E pressure (SE) is not applied to the lock-up shift valve. The lock-up shift valve stays in the right side to uncover the ports of torque converter pressure leading to the left side of the torque converter and releasing from the right side of the torque converter. Torque converter pressure (92) changes to (94) at the lock-up shift valve, and enters into the left side of the torque converter to disengage the torque converter clutch. The torque converter clutch piston keeps away from the torque converter cover, the torque converter clutch lock-up is OFF.

    NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.


    System Description (cont'd)14-62

    Partial Lock-up

    As the speed of the vehicle reaches the prescribed value, shift solenoid valve E is turned ON by the PCM, and shift solenoid valve E pressure (SE) is applied to the right side of the lock-up shift valve. The lock-up shift valve is moved to the left side to switch the port of torque converter pressure (91) leading to the right side of the torque converter, and the port of torque converter pressure (94) releasing from the left side of the torque converter. Torque converter pressure (91) flows to the right side of the torque converter to engage the torque converter clutch. The PCM also controls the A/T clutch pressure control solenoid valve A to regulate A/T clutch pressure control solenoid valve A pressure (55) applying to the lock-up shift valve and lock-up control valve. The position of the lock-up control valve depends on A/T clutch pressure control solenoid valve A pressure (55) and torque converter pressure released from the torque converter. The lock-up control valve controls volume of the torque converter clutch lock-up conditions until fluid between the clutch piston and torque converter cover is released fully; the torque converter clutch partial lock-up condition.

    NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.


    14-63

    Full Lock-up

    When the vehicle speed further increased, the PCM controls the A/T clutch pressure control solenoid valve A to increase A/T clutch pressure control solenoid valve A pressure (55), and the lock-up control valve is moved to the left by pressure increased amount. Torque converter pressure (94) from the left side of the torque converter is released fully at the lock-up control valve, and torque converter pressure (91) engages the torque converter clutch securely; the torque converter clutch full lock-up condition.

    NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
