- Transmission Fluid Drain and Refill
General Procedures
Removal
Installation
Special Tool(s)

Syringe 1. Raise the vehicle for access.

2. NOTE: This procedure will not re move residual fluid from the
torque converter.
Drain the transmission fluid.
2. WARNING: TRANSMISSION FLUID MAY CAUSE
SEVERE BURNS, ENSURE THAT ALL SAFETY PROCEDURES
ARE OBSERVED AND THAT THE RECEPTACLE FOR WASTE
HAS SUFFICIENT CAPACITY.
Carefully remove the drain plug and drain the
transmission fluid.

3. Refit the drain plug and tighten to the specified torque figure.
Use a new O-ring.

1. Remove the fluid level / filler plug.
2. Using a syringe dedicated to tran smission fluid only (not used
for any other type of oil or fluids ), inject transmission fluid until

it overflows from the plug orifice. 2. CAUTION: It is essential that only the specified
fluid is used.
Wait until the flow of fluid has reduced to a trickle.

3. Fit, but do not tighten the plug.
4. Prepare PDU (at the base station).
1. Install the appropriat e disk and switch ON.
2. Select the vehicle specification - ENTER.
3. From Engineering Tools select Toolbox - ENTER.
4. From Toolbox select Powertrain - ENTER.
5. Connect MPA and download cable to PDU and base station.
6. Select Datalogger - ENTER.
7. Select Transmission - ENTER.
8. Disconnect download cable.
9. Connect MPA to PDU.
5. Connect PDU (at the vehicle).
1. Connect MPA cable to the vehicle diagnostic socket -
ENTER.
2. Energize the vehicle ignition - ENTER.
3. From the menu select Transmission oil temperature (TOT) - ENTER.
4. Check that the fluid temperature is <30°C.
6. From above.
7. NOTE: Ensure that the TCM is connected and functioning
correctly.
Select Park and start the engine.

8. Cycle the gear selector.
From P to D.
From D to R.
From R to P.
9. From below.

10. Adjust the transmission fluid level.
1. Remove the filler / level plug.
2. Inject fluid until it ove rflows from the plug orifice.
10. CAUTION: The fluid temperature MUST NOT
exceed 50°C.
Wait for the flow of fluid to re duce to a trickle (for at least
1 minute).
11. Refit the filler / level plug and tighten to the specified torque
figure.
