6. Unscrew 13 fixing screws (head diameter 12 mm) with Torx insert T 27 and lower control unit only so far as to guarantee that the wiring harness is not subjected to any tension.

Place the control unit on a suitable surface (e.g. transmission jack).

Note

Do not allow the control unit to hang from the wiring harness under any circumstances.

7. Mark the push-on sleeves for re-installation and pull off from the solenoid valves.

8. Pull the wiring harness out of the holding clamps and remove the control unit.

Installing

Installation takes place in reverse order.

1. Tightening torques: Control unit to transmission = 8 Nm (6 ftlb)

ATF strainer to control unit ATF pan to transmission Drain screw to ATF pan Hollow screw to ATF pa

= 8 Nm (6 ftlb) : 6 Nm (4 ftlb) ■40 Nm (29 ftlb) =40 Nm (29 ftlb)

2. Push on push-on sleeves for solenoid valves up to the stop. Pay attention to cable colors.

3. Mount the control unit so that the pin of the notched disk projects into the recess of the selector slide.

4. Screw in the fixing screws for the control unit and counter slightly. Pay attention to screw lengths.

A = Screw length 80 mm B = Screw length 65 mm C = Screw length 115 mm D = Screw length 60 mm

5. Position control unit. To do this, move notched disk to position 1 (1st gear) and push control unit back until it rests against the notched disk. Tighten fixing screws with 8 Nm in this position.

7. Fit ATF strainer with O-ring. Tightening torque 8 Nm.

8. Place two magnets in the beads of the ATF pan, fit seal and secure the pan with the holding brackets so that the short legs press onto the ATF pan.
