Special Tool(s)

Lifting handle
307-139
1. Remove the transmission unit from the vehicle; 44.20.01.

2. Remove the torque converter from the transmission unit.
Install lifting handles 307 - 139.
3. Remove lifting handles 307 - 139 from the torque converter.
4. Clean the torque conver ter and mating faces.

5. CAUTIONS:
Use extreme care NOT to damage the oil seal with the
converter spigot.
Ensure that the conver ter is fully located.
Install the torque converter.
1. Install lifting handles 307 - 139.
2. Lubricate the front pump seal.
To facilitate location, rotate the converter as it is being
fitted and note the engagement of splines and oil pump
drive.
6. Check that the three conver ter fixing boss faces are
approximately 8,0 mm proud of the transmission mounting
face.
7. Remove lifting handles 307 - 139 from the torque converter.
8. Install the transmission unit; refer to Operation 44.20.01,
noting especially the alignment instructions.

In the event of a system fault, the TCM will adopt 'limp home' mode.
Electrical control
Refer to Section 307-01B.
Transmission Control Components
Transmission Control Module (TCM)
The TCM controls the transmission internal components thus determining gear selection and shift pattern.

The TCM is located in the same housing as the engine control module (ECM) and is accessed in the same manner. With the
two connectors unplugged the TCM may be withdrawn, complete with mounting bracket. The mounting bracket is secured to
the TCM by 2 locknuts.
Operation
CAUTION: Disconnection of OTHER contro l module connectors and / or the vehicle battery, may introduce fault codes
(DTCs). Following rectification and reconnection, ensu re that no induced codes exist in the TCM memory.
The TCM processes input and output in both analogue and di gital form which may be summarized in four categories:
Input Signals
Gear selector position (Dual Linear Switch x 4 inputs see 307.05) Transmission oil temperature Kickdown Speed sensor #1 Speed sensor #2 Mode switch

Fluid Drain and Refill
General Procedures
Special Tool(s)

Dipstick
307-379
1. Disconnect the battery ground lead.
2. Raise the vehicle for access.

3. NOTE: This procedure will not re move residual fluid from the
torque converter.
Drain the transmission fluid.
3. 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 pl ug and discard the sealing
washer.

4. Refit the drain plug and tighten to the specified torque figure.
Use a new sealing washer.
5. Connect the PDU to monitor the fluid temperature.
6. Access the dipstick tube.
1. Break off the dipstick tube plug locking plate.
2. Push the locking pin downward, into the plug.
3. Remove the dipstick tube plug.
Push the locking pin through the tube plug and discard the
pin.

10. Cycle the gear selector:
From P to D.
From D to R.
From R to P.

11. NOTE: Temperature will ONLY be displayed in D or R.
Check the transmission fluid temperature to select the
appropriate dipstick calibration. 1. MAX and MIN marks at 25°C fluid temperature.
2. MAX and MIN marks at 80°C fluid temperature.

12. Check the transmission fluid level.
Insert the dipstick (special tool 307 - 379) until it stops
(tip contact with the fluid pan).
Remove the dipstick an d check the level.
• NOTE: Only use a lint free cloth to wipe the dipstick.
Repeat this operation.
13. Correct the fluid leve l as required, noting that excess fluid
MUST be removed.
14. STOP the engine and remove the dipstick.
15. Seal the dipstick tube.
1. Seat the tube plug.
2. Engage and fully seat the new locking pin.
