Special Tools
* J 24204-2 - Bar and Stud Assembly
* J 36850 - Transjel(R) Lubricant
* J 44530 - Clutch Piston Spring Compressor

For equivalent regional tools, refer to Special Tools (Allison - Automatic Transmission).




1. Position the transmission case so that the rear of the case is facing up.
2. Apply J 36850 - Transjel(R) LubricantJ 36850 or an equivalent lubricant to the inside and outside diameters of the new 2-6 clutch piston assembly (1).
3. Align the new 2-6 clutch piston assembly (1) so that the seal is facing down and the 1.016 mm (0.040 in) lubrication/cooling orifice is positioned at the top of the transmission case.
4. Install the 2-6 clutch piston assembly (1).
5. Gently tap the piston until the piston seats.




6. Align the input internal ring gear (1) so that the outside splines are facing down.
7. Install the input internal ring gear (1).
8. Rotate the ring gear until the 3rd, 5th, and reverse fiber plates are engaged.
9. Make sure the input internal ring gear (1) is seated against the thrust plates of the 3rd, 5th, and reverse clutch backing plate assembly.




10. Install the input carrier module (2).
11. Rotate the input carrier module until the module drops into place.

Caution: Installing the thrust bearing incorrectly may cause permanent damage to the transmission.

12. Align the thrust bearing (1) so that the blue stripe on the thrust bearing is facing away from the input carrier module (2).
13. Install the thrust bearing (1) onto the input carrier module (2).




14. Align the 2-6 clutch piston return spring assembly (3) with the spring assemblies up.
15. Install the return spring assembly (3) into the transmission case.
16. Starting with a 2-6 clutch fiber plate, alternately install six 2-6 clutch fiber plates (1) and six 2-6 clutch steel plates (2).




17. Install the 2-6 clutch backing plate (1).





Caution: Refer to 3-5 Reverse Clutch Backing Plate Rivet Damage Caution (3-5 Reverse Clutch Backing Plate Rivet Damage Caution).

18. The threaded rod of J 24204-2 - assembly must pass through but not touch the bushing.
19. Install J 24204-2 - assembly (1) and J 44530 - compressor (2) into the transmission case.
20. Make sure J 24204-2 - assembly does not touch the gear thrust plate rivets (6) on the 3rd, 5th, and reverse clutch backing plate assembly.
21. Compress the piston return spring assemblies (5) until the retaining ring groove is visible.

Note: The outer 2-6 clutch retaining ring is thinner and larger in circumference compared to the inner low and reverse clutch retaining ring.

22. Install the 2-6 clutch retaining ring (4).

Note: Position the 2-6 clutch and the low and reverse clutch retaining ring gaps 180 degrees apart.

23. Install the low and reverse clutch retaining ring (3) with the retaining ring gap 180 degrees from the 2-6 clutch retaining ring gap.

Note: DO NOT damage the input carrier bushing when removing J 24204-2 from the transmission case. The threaded rod of J 24204-2 must pass through but not touch the bushing.

24. Remove J 24204-2 - assembly and J 44530 - compressor from the transmission case.
