Automatic Transmission/Transaxle: Service and Repair

Removing and Installing Automatic Transmission










Tools

Removing

1. Remove battery.




2. Unscrew self-locking hexagon nuts from spring struts in trunk.




3. Disconnect multiple plug in spare wheel well and pull out toward rear.




4. Detach parking brake cable and lock.

5. Remove wheel wells.




6. Unscrew air duct.




7. Turn crankshaft until converter drain plug can be seen. Now unscrew drain plug and drain ATF.




8. Unscrew oil filler tube from oil pan and drain ATF.




9. Unscrew feed and return lines for ATF cooler.




10. Remove cross member.








11. Remove exhaust system from primary muffler.




12. Remove exhaust system guards.

13. Remove battery console.




14. Remove rubber cap from sight hole in central pipe and turn crankshaft to position double clamp that capscrew can be removed.

15. Detach brake calipers and suspend that brake hoses are without tension.

16. Detach axle shafts from transmission and suspend in horizontal position.

17. Detach holder for parking brake cable and pull out cable toward rear.




18. Remove rear reinforcement plate.




19. Detach stabilizer from lower control arm.




20. Support transmission on stabilizer bar with Special Tool 9164.




21. Remove two bolts from transmission mounts and two bolts holding rear axle cross member to frame.




22. Mark position of toe eccentric bolts for reinstallation and remove eccentric bolts.




23. Mark position of rear axle crossmember for reinstallation.




24. Place jack underneath rear axle cross member and remove mounting bolts from cross member.

25. Lower rear axle carefully and be careful that spring struts, cross member and bearing brackets do not tilt.

Note:A second person is required for removal of rear axle.

26. Mount Special Tool 9163 on universal transmission lift and place underneath transmission.

27. Lift transmission and detach Special Tool 9164.




28. Lower transmission a little, detach selector lever cable and disconnect cable sleeve.




29. Pull off vacuum line from vacuum modulator and press out of holders. Detach transmission cable and remove holder for guide tube.




30. Remove six bolts of central tube. This requires lowering transmission as far as possible.




Note: When lowering transmission, be careful that check valve for air injection does not damage brake line.

31. Pull transmission out of coupling splines and lower carefully.


Front Convertor Housing, Exchanging

Note: Before installing new automatic transmission/final drive assembly into vehicle, front convertor housings must be exchanging between new and old units. This is to maintain factory adjustment between drive shaft coupling and transmission input shaft.




Perform the following steps:

1. Loosen 6 bolts (2) attaching drive plate to torque convertor (1) through opening (arrow).

2. Remove 8 bolts holding front torque converter housing (A).

3. Exchange front torque convertor housings only.

4. Tighten convertor housing bolts to (14 - 17ft lb).

5. Tighten drive plate bolts to (23 - 28ft lb).

Installing




1. Move central tube to installed position with a suitable piece of wood. Install rear reinforcement plate for car lifts without a center pillar.




2. Lift transmission with universal transmission lift and Special tool 9163, and push it into splines of coupling.

3. Install accessible bolts on central lube and tighten hand tight.

4. Lift transmission and remove piece of wood from central tube.

5. Lower transmission until all bolts can be installed on central tube flange.

6. Tighten six mounting bolts to specified torque.

7. Lift transmission again so selector lever and transmission cables can be installed without tension.





8. Lift transmission and hold in installed position with Special Tool 9164.

9. Push up wire harness through opening in spare wheel well and install rubber grommet.

10. Lower universal transmission lift.

11, Position rear axle and tighten all bolts except for the two transmission mount bolts.

Note: A second person is required to install rear axle.




12. Lift transmission and detach Special Tool 9164.

13. Mount transmission on cross member and tighten all bolts to specified torque.

Note: Watch marks for correct reinstallation.
