Special Tools:






NOTE: If the input clutch assembly is being reconditioned (clutch/seal replacement) or replaced, it is necessary to perform the Quick Learn Procedure using the scan tool TCM Quick Learn

1. Mount input clutch assembly to Input Clutch Pressure Fixture (Tool ).
2. Tap down (2) reverse clutch reaction plate (4) to release pressure from snap ring.

3. Remove reverse clutch snap ring (3)(Figure 2).










4. Pry up reverse clutch reaction plate (1)(Figure 3).










5. Remove reverse clutch reaction plate (1)(Figure 4).










NOTE: Tag reverse clutch pack for reassembly identification.

6. Remove the reverse clutch pack (two fibers/one steel) (1, 2)(Figure 5).










7. Remove the OD/Reverse reaction plate (1) snap ring (3)(Figure 6).










8. Remove OD/Reverse pressure plate (1)(Figure 7).










9. Remove OD/Reverse reaction plate wave snap ring (2)(Figure 8).










10. Remove OD shaft/hub and OD clutch pack (1)(Figure 9).










NOTE: Tag overdrive clutch pack for reassembly identification.

11. Remove the overdrive clutch (1, 3) from the overdrive hub/shaft (2)(Figure 10).










12. Remove and inspect number 3 and 4 thrust plates (1, 3)(Figure 11).










13. Remove the underdrive shaft assembly (2)(Figure 12).










14. Remove the number 2 needle bearing (1)(Figure 13).










15. Remove the OD/UD reaction plate tapered snap ring (1)(Figure 14).










NOTE: The OD/UD clutch reaction plate has a step on both sides. The OD/UD clutches reaction plate goes tapered step side up.

16. Remove the OD/UD reaction plate (1)(Figure 15).










17. Remove the first UD clutch disc (1)(Figure 16).










18. Remove the UD clutch flat snap ring (1)(Figure 17).










NOTE: Tag underdrive clutch pack for reassembly identification.

19. Remove the UD clutch pack (1, 3)(Figure 18).










CAUTION: Compress return spring just enough to remove or install snap ring.

20. Using Compressor (4) and an arbor press (2), compress UD clutch piston enough to remove snap ring (3)(Figure 19).










21. Remove the underdrive spring retainer snap ring (2), spring retainer (1), and spring (4)(Figure 20).










22. Remove the UD clutch piston (1)(Figure 21).










23. Remove the input hub tapered snap ring (2)(Figure 22).










24. Tap on input hub (1) with soft faced hammer (2) and separate input hub from OD/Reverse piston and clutch retainer.










25. Separate the input hub from OD/Reverse piston (5) and clutch retainer (2)(Figure 24).










26. Separate clutch retainer (2) from OD/Reverse piston (1)(Figure 25).










27. Using Disc (4) and an arbor press (1), compress OD/Reverse piston (5) return spring just enough to remove snap ring (3)(Figure 26).










28. Remove the OD/Reverse piston return spring (2) and snap ring (3)(Figure 27).










29. Remove input shaft (1) to input clutch hub snap ring (3)(Figure 28).










30. Using a suitably sized socket (2) and an arbor press (1), remove input shaft (5) from input shaft hub.
