ADJUSTMENTS
HYDRAULIC SYSTEM
The procedures detailed below should be followed in the event that the self test procedure detailed in section 6, or a
defect symptom, indicates that there is a fault in the hydraulic system.
When making adjustments to the transmission, select the appropriate procedures from the following preliminary
checks.
lConduct a transmission fluid test procedure, refer to section 7.2.
lCheck the manual linkage adjustment (refer to the vehicle workshop manual).
lCheck engine idle speed (refer to Section 7.3).
lConduct a stall test (it is outside the scope of this publication to detail this procedure)
lconduct a road test (it is outside the scope of this publication to detail this procedure).
TRANSMISSION FLUID TEST PROCEDURE
Checking Transmission Fluid Level
This procedure is to be used when checking a concern with the fluid level in a vehicle. A low fluid level will result in
gearshift loss or delay if driven when the vehicle is cold.
The vehicle is first checked for transmission diagnostic messages (refer to section 6). If the vehicle has a speedo fault
it is possible for the oil level to be low.
The vehicle is to be test driven to determine if there is an abnormal delay when selecting drive or reverse, or loss of
drive. One symptom of low oil level is a momentary loss of drive when driving the vehicle around a comer. Also when
the transmission fluid level is low, a loss of drive may occur when the transmission oil temperature is low.
If there is no loss of drive when the vehicle is driven warm and a speedo fault is registered, then fluid should be added
to the transmission.
Checking, Adding Fluid and Filling
When adding or changing transmission oil use only Castrol TQ 95 automatic transmission fluid (ATF) or other approved
fluids. The use of incorrect oil will cause the performance and durability of the transmission to be severely degraded.
Do not underfill the transmission. Incorrect tilling may cause damage to the transmission. The fluid level setting
procedure is detailed below.
Notice
When a transmission is at operating temperature hot transmission fluid may come out of the case if the fill plug is
removed. 9 the transmission is at operating temperature allow two hours for cooling prior to removing the plug.
1. If the vehicle is at operating temperature allow the vehicle to cool down for two, but no greater than four hours
before adding transmission fluid (this will allow the transmission to be within the correct temperature
range).
While hot the ATF level is higher and removing the plug may result in oil being expelled from the filler hole. This
will result in the level being low.
2. The transmission selector is to be in Park.
Switch the engine off.
3. Raise the vehicle on a hoist (or leave over a service pit).
4. 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.
5. Lower the vehicle with the filler pump still connected and partially fill the transmission.
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.
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
a small quantity of ATF to the correct level.
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
a small quantity of ATP to the correct level.
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
trouble message, it may be re-established by the following procedure.
lCheck that the hot engine idle speed is within specification.
lAllow 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
throttle reference point in the TCU has now been set.

Torque Converter and Housing Assembly
To assemble the torque converter and housing assembly,
proceed as follows.
1. Locate the torque converter housing on the transmission
main case.
2. Install and tighten the securing bolts to specification.
Notice
All the hardware must be correctly installed and torqued to
specification.
3. Fit the converter ensuring that the tangs are engaged in
the pump gear. Ensure that the tangs do not contact the
pump seal.
