Tools Required

1. Inspect the forward clutch housing (433) for the following:

•	Plugged feed passages

•	Damaged ball check valve (434)

•	Worn or damaged splines

•	Seal ring groove nicks or burrs

•	Cracked or blocked fluid passages in the input shaft

•	Worn or damaged clutch plates

2. Inspect the input shaft fluid seals (431, 432) for worn or damaged seals.
3. Slide J 45130-3  (2) over the input shaft, and position J 45130-3  (2) at the seal groove closest to the housing. Coat J 45130-3  (2) with transmission fluid.
4. Guide a NEW seal (431) onto J 45130-3  (2) and slide the seal into the groove with J 45130-2  (1).



5. Remove J 45130-3 (2).
6. Install the input shaft fluid seals (432).



7. Size the seals (431, 432) with J 45130-1 .
8. Leave J 45130-1 in place for at least five minutes. If possible, leave J 45130-1 in place until you install the assembly into the transmission case.



9. Inspect the forward piston and the coast clutch piston for the following:

•	Cracks or damage to seal grooves

•	Wear on the piston

•	Worn or damaged clutch plates

10. Use J 45134 to install the forward clutch piston (436).



11. Use J 45132 to install the coast clutch piston (438).



12. Inspect the forward and coast clutch piston spring for the following:

•	Damaged cage

•	Distorted or missing springs

13. Install the piston spring (439).
14. Use J 43074 to compress the spring and install the NEW retainer ring (440).



15. Measure the distance from the top of the forward clutch housing to the coast clutch piston (438), record this as dimension C.
16. Measure the distance from the top of the forward clutch housing to the forward clutch piston (436), record this as dimension B.
17. Subtract dimension C from dimension B. This is now dimension A.



18. Install the coast clutch backing plate (445) into the coast clutch housing (446).
19. Install the coast clutch plates into the coast clutch housing (446). Starting with the coast clutch plate (443) with outer splines. Alternating with the coast clutch plate (444) with inner splines. Refer to Clutch Plate Selection Specifications .
20. Install the coast clutch apply plate into the coast clutch housing (446).
21. Install the coast clutch spacer plate (441) into the coast clutch housing (446).
22. Measure the distance from the top of the coast clutch housing (446) to the top of the coast clutch spacer plate (441), record this as dimension B.
23. Subtract dimension B from dimension A, this is clutch pack travel. If the clutch travel is between 0.77 mm (0.030 in) and 1.67 mm (0.060 in) use the current coast clutch spacer plate (441). If the clutch travel is more than 1.67 mm (0.060 in) use the next size larger coast clutch spacer plate (441). If the clutch travel is less than 0.77 mm (0.030 in) use the next size smaller coast clutch spacer plate (441).



24. Install the coast clutch spacer plate (441).
25. Install the coast clutch apply plate (442).
26. Install the coast clutch plates. Starting with the coast clutch plate (443) with the outer splines. Refer to Clutch Plate Selection Specifications .
27. Alternating with the coast clutch plate (444) with inner splines.
28. Install the coast clutch backing plate (444).
29. Install the coast clutch housing (446).



30. Install the forward clutch apply plate (447).
31. Install the forward clutch plates. Starting with the forward clutch plate (448) with outer splines. Alternating with the forward clutch plate (449) with inner splines. Refer to Clutch Plate Selection Specifications .
32. Install the forward clutch backing plate (450).
33. Install the forward clutch backing plate retainer ring (451).



34. Measure the distance between the forward clutch backing plate and the bottom of the gage bar. Measure three times in different locations on the backing plate. Record this as H1.
35. Apply air pressure to the specified port. Measure the distance between the forward clutch backing plate and the bottom of the gage bar. Measure three times in different locations on the backing plate. Record this as H2.
36. Subtract H2 from H1 this is the clutch pack travel. If the clutch travel is between 1.86 mm (0.073 in) and 1.06 mm (0.042 in) use the current forward clutch backing plate retainer ring (451). If the clutch travel is more than 1.86 mm (0.073 in) use the next size larger forward clutch backing plate retainer ring (451). If the clutch travel is less than 1.06 mm (0.042 in) use the next size smaller forward clutch backing plate retainer ring (451). Refer to Clutch Piston Travel Specifications .
37. At this time you do not install the forward and coast clutch assembly (7) into the transmission case. Set aside until told to do so.
