5. NOTE: Coat the reverse clutch piston seals with petroleum jelly.
Install the reverse clutch piston in the case until it is fully seated in the case.
6. Install the reverse clutch return spring assembly.
7. NOTICE: Do not over compress the return spring or damage to the spring will occur.
Using the Clutch Spring Compressor Aligner and the Clutch Spring Compressor, install the reverse clutch return spring snap ring.
8. NOTE: The use of petroleum jelly will hold the No. 17 thrust bearing in place during assembly.
For transmissions equipped with a slip yoke, install the No. 17 park gear thrust bearing.
9. NOTE: The use of petroleum jelly will hold the No. 17 thrust washer in place during assembly.
For transmissions equipped with a fixed yoke, install the No. 17 park gear thrust washer.
10. NOTICE: Be careful when installing the output shaft not to damage the seals or a transmission leak could occur.
Install the output shaft.
11. NOTICE: The Torx screw has a threadlocking compound. If the screw is removed, it must be discarded and a new screw installed.
If removed, install the parking pawl abutment with a new Torx screw.
- Tighten to 25 Nm (18 lb-ft).
12. Install the parking pawl.
1. Install the parking pawl shaft.
2. Install the parking pawl.
3. Install the parking pawl return spring.
13. NOTE: Make sure the dimple on the parking guide support plate is facing inward.
Install the parking rod guide plate.
1. Install the parking rod guide plate.
2. Install the bolts.
- Tighten to 25 Nm (18 lb-ft).
14. Install a new orifice lube plug in the rear of the case. Using a 12 mm (0.472 in) socket, tap the orifice lube plug into the back of the transmission. Check to make sure that the orifice lube plug is fully seated into the back of the transmission.
15. Install a new extension housing gasket.
Transmissions equipped with a fixed flange
16. Install the extension housing and 9 extension housing bolts.
- Tighten to 48 Nm (35 lb-ft).
Transmissions not equipped with a fixed flange
17. Install the extension housing and 9 extension housing bolts.
- Tighten to 48 Nm (35 lb-ft).
All transmissions

19. Install the Transmission Range (TR) sensor, park rod assembly and loosely install the bolts.
20. Install the manual control lever.
21. Install the roll pin into the case.
22. Install a new roll pin. Leave 2 mm (0.08 in) of the pin exposed.
23. Tighten the TR sensor bolts.
- Tighten to 10 Nm (89 lb-in).
Transmissions equipped with a fixed flange
24. Using the Transmission Extension Housing Seal Installer, install a new extension housing seal.
25. Inspect the new output shaft nut O-ring for cuts. A new nut must be installed.
26. Using the Output Shaft Locknut Socket, install a new output shaft retaining nut.
- Tighten to 200 Nm (148 lb-ft).
27. Install the output flange and a new bolt.
- Tighten to 130 Nm (96 lb-ft).
Transmissions not equipped with a fixed flange
28. Install a new extension housing seal using the Output Shaft Seal Installer.
All transmissions
29. Install the No. 16 bearing and race.
30. Assemble the rocker clutch and ring gear assembly.
1. Install the No. 15 hub bearing onto the ring gear hub.
2. Install the rocker clutch, low/reverse clutch pack and carrier and hub assembly into the output hub and ring gear assembly.
31. NOTE: Place the transmission in the horizontal position.
Install the rocker clutch and ring gear assembly into the transmission case.
32. NOTICE: Do not apply air pressure to move the low/reverse piston without first installing the friction plates and the snap ring, or damage to the snap ring will occur.
Install a new flat snap ring and make sure that the snap ring is fully seated in the case snap ring groove.
Install a new flat snap ring so the tang ends are in the gaps to the right and to the left of the case spline as shown.
- Check the function of the reverse clutch by applying air to the correct passage (through the case valve body worm trail) for the reverse clutch.
33. Using the Adapter and the Transmission Forward Clutch Assembly Installer, install the forward geartrain as an assembly.
34. Install the intermediate clutch pressure plate.
- Position the intermediate clutch pressure plate in the case with the 3 tabs facing downward.
35. Install the intermediate clutch plates, starting with a friction plate.
36. Install the center support with the transmission in a vertical position to avoid damage to the center support Teflon(R) seals.
37. Loosely install the center support feed bolts.
