5A-80 AUTOMATIC TRANSMISSION 6. Switch off the engine and raise the vehicle on the hoist, if applicable, ensuring that the vehicle is level. 7. Three minutes after the engine has stopped, but no longer than one hour, remove the filler pump, The correct level is reached when ATF is aligned with the bottom of the filler hole. If the correct level is not reached, then add 8. Replace the transmission filler plug and clean all remnants of ATF on the transmission and vehicle. 9. Tighten the transmission filler plug to specification. Checking, Adding Fluid and Filling - Drained or Dry Transmission To set the correct fluid level proceed as follows. 1. Set the transmission selector to Park and switch the engine off. 2. Raise the vehicle on a hoist (or leave over a service pit). 3. Clean all dirt from around the service fill plug prior to removing the plug, Remove the oil service fill plug. Clean the fill plug and check that there is no damage to the ‘O’ ring. Install the filler pump into the filler hole. 4. Lower the vehicle with the filler pump still connected and partially fill the transmission. This typically requires approximately : a. If the transmission torque converter is empty: 9.0 litres - 4WD 9.0 litres - RWD b. If the transmission torque converter is full: 4.5 litres - 4WD 4.5 litres - RWD 5. Start the vehicle in Park with the Parking brake and foot brake applied with the engine idling, cycle the transmission gear selector through all positions, adding ATF until gear application is felt. 6. Then add an additional 0.5 litres of ATF. 7. Switch off the engine and raise the vehicle on the hoist. Remove the filler pump and replace the filler plug. The plug shall be tightened to specification. 8. The vehicle is then to be driven between 3.5 and 4.5 kilometers at light throttle so that the engine does not exceed 2500 rpm. This should result in the transmission temperature being in the range 50 to 60°C. 9. With the engine idling, cycle the transmission selector through all gear positions with the brake applied. 10. Stop the engine. Raise the vehicle on the hoist, if applicable ensuring the vehicle is level. 11. Three minutes after the engine has stopped, but no longer than one hour, remove the filler plug. The correct level is reached when ATF is aligned with the bottom of the filler hole. If the correct level is not reached, then add 12. Replace the transmission filler plug and clean all remnants of ATF on the transmission and vehicle. Tighten the transmission Filler plug to specification. ELECTRONIC ADJUSTMENTS Idle Speed Adjustment Carry out the adjustments to the idle speed as detailed in the workshop manual. Throttle Position Calibration Should the throttle position data stored in the TCU be lost or be out of specification, as indicated by a diagnostic l Check that the hot engine idle speed is within specification. l Allow the engine to idle in ‘Drive’ for 60 seconds with the air conditioner (if fitted) turned off. The closed throttle reference point in the TCU has now been set. Switch the engine off but leave the ignition on. Hold the accelerator pedal on the floor for 60 seconds. The wide open |
