Removal

Note

When the solenoids are removed and fitted, the control unit may remain installed.

To replace solenoids 1, 2 and 3, however, the solenoid housing (1) must be removed.

The installation position of solenoid 4 is shown on page 38-211.

2. Pull connector sleeves off the solenoids.

3. Screw out fastening screws and and take off valve housing complete with valves. (Transmission is removed in figure)

Specification: 0.1...0.3 mm Note

The end play must be checked whenever the transmission is assembled and must be corrected with adjusting shim No. 8 (see page 38 - 224) if required.

1. Assemble transmission fully and fit dial gauge with Special Tool 9356 to the turbine shaft. Make sure the measuring surface of the dial gauge rests on the stator shaft.

Set dial gauge to "0" and pull at Special Tool to determine end play.

Fit a thicker or thinner shim as required if the reading deviates from the specification.

Removal and refitting notes Removal

1. Remove transmission, torque converter and drive shaft (refer to pages 37 - 201,

32 - 201, 39 - 208) and attach transmission with bracket 9343 to the assembly stand so that the ATF pump faces up.

2. Remove torque converter oil seal .

3. Mark installation position of ATF for reassembly and undo mounting bolts (Torx T 27).

1827-38

4. Pull ATF pump out of housing using Special Tool 9352 and take off pump carefully.

Note

This operation must be carried out very carefully to prevent the inner transmission components slotted in place from being pulled out at the same time.

A = Tighten only finger-tight

5. Do not turn transmission on assembly stand (to prevent inner components from dropping out).

Installation

1. Pull freewheel ass. off the cylinder of clutch B.

2. Use a depth gauge to check inner transmission components. Assembly is correct if the upper edge of cylinder B is approx.

10 mm below the step in the transmission housing and the engine shaft protrudes approx. 22 mm beyond the turbine shaft.

3. Install freewheel into correct position of internal splines of brake C.

Note

The freewheel assembly must be fitted in such a way that the flange of the inner race faces the ATF pump.

4. Turn transmission on assembly stand so that the transmission opening points slightly upwards.

Note

Under no circumstances must the transmission opening point down as this would cause the transmission parts to drop out.

5. Install pump assembly complete with freewheel carefully. Make sure that the freewheel assembly does not slip out of the splines.

6. Turn transmission on assembly stand so that the ATF pump faces up.

Note

Assembly is correct if the pump unit rests with a slight spring preload on the housing and the turbine shaft protrudes approx. 18 mm beyond the stator shaft.
