Automatic Transmission

DISASSEMBLY





1. Remove the torque converter (1).





2. Place the transmission in a vertical position.
3. Measure the input shaft end play as follows.
a. Attach the Special Tool 8266-18 (2) to Special Tool 8266-8 (1).
b. Attach the Special Tool C-3339 (3) and the Special Tool 8266-8 (1).
c. Install the assembled tool onto the input shaft of the transmission and tighten the retaining screw on Special Tool 8266-18 (2) to secure it to the input shaft.
d. Position the dial indicator plunger against a flat spot on the oil pump and zero the dial indicator.
e. Move the input shaft in and out. Record the maximum travel for assembly reference.





4. Loosen the guide bushing (12) and remove it from the transmission housing.
5. Remove the oil pan (5).
6. Remove the oil filter (4).
7. Unscrew the bolts (3) and remove the electrohydraulic unit (2).
8. Place the transmission in the PARK position before attempting to remove the output shaft nut.
9. Remove the output shaft nut holding the propeller shaft flange to the output shaft.
10. Remove the propeller shaft flange.
11. Remove the transmission rear oil seal with a suitable slide hammer and screw.
12. Remove the transmission output shaft washer. Be sure to tag the washer since it is very similar to the geartrain end play shim and they must not be interchanged.





13. Remove the transmission rear output shaft bearing retaining ring (1).





14. Position Special Tool 9082 (1) over the inner race of the output shaft bearing (3).





15. Slide the collar (3) on Special Tool 9082 (1) downward over the fingers of the tool (4).





16. Remove the output shaft bearing (3).
17. Remove the geartrain end-play shim from the output shaft. Be sure to tag the shim since it is very similar to the output shaft washer and they must not be interchanged.
18. Remove the bolts holding the transmission housing to the torque converter housing from inside the converter housing.
19. Stand the transmission upright on the converter housing. Be sure to use suitable spacers between the bench surface and the torque converter housing since the input shaft protrudes past the front surface of the housing.
20. Remove the remaining bolts holding the transmission housing to the torque converter housing.
21. Remove the transmission housing from the torque converter housing.





22. Remove the output shaft with the center and rear gear set and clutch K3 (3).
23. Remove the thrust needle bearing (4) and the thrust washer (5).
24. Remove the drive shaft with driving clutch K2 and front planetary gear set (6).
25. Remove the driving clutch K1 (1).





26. Unscrew the bolts (4) and remove the oil pump (6). Screw two opposed bolts into the oil pump housing and press the oil pump out of the converter housing by applying light blows with a plastic hammer.
27. Remove and discard the torque converter hub seal and the oil pump outer O-ring seal from the oil pump.
28. Unscrew the bolts (1) and remove the multi-disc brake B1 (5) from the torque converter housing. Screw two opposed bolts into the multi-disc brake B1 (5) and separate from the torque converter housing by applying light blows with a plastic hammer.
29. Detach the intermediate plate (3) from torque converter housing (2).





30. Unscrew the bolts (7).
31. Remove the snap-ring (1), then remove the multi-disc holding clutch B3 discs (2) from the transmission housing (6). The externally toothed disc carrier for the multi-disc holding clutch B2 (4) is also the piston for the multi-disc holding clutch B3 discs (2).
32. Remove the parking lock gear (5).
