Transmission 2nd and 4th Clutch Piston Retainer - Assembly
ASSEMBLY
NOTE: Clean and inspect all components. Replace any components which show evidence of excessive wear or scoring.
1. Lubricate all seals with Mopar(R) ATF +4 prior to installation.
NOTE: The 4C piston installation aid is only available with procurement of a new 4C piston.
2. Insert the installation aid (1) into the 4C retainer / bulkhead (2).
3. Lubricate the inner and outer 4C piston seals (3) with MOPAR(R) ATF+ 4.
4. Install the 4C piston (3) into the installation aid (1).
5. Push the 4C piston (3) down evenly until it is seated in the 4C retainer / bulkhead (2).
6. Remove the installation aid (1) from the 4C retainer / bulkhead (2).
7. Position the 4C piston return spring onto the 4C piston.
8. Using Spring Compressor 8250 (2) and a suitable shop press (1), compress the 4C piston return spring and install the snap-ring.
9. Assemble and install the 4C clutch pack (2, 3) into the retainer/bulkhead (11) with a steel separator plate against the piston.
10. Install the 4C reaction plate (7) and snap-ring (6) into the retainer/bulkhead (11). The 4C reaction plate is non-directional.
11. Measure the 4C clutch clearance. The correct clutch clearance is 0.770-1.390 mm (0.030-0.055 in.). The snap-ring (6) is selectable. Install the chosen snap-ring and re-measure to verify the selection.
The 4C selectable snap ring thickness are as follows:
4C SELECTABLE SNAP RING THICKNESS
- One Butterfly End, One Square End = 1.79 mm (0.070 in.).
- Both Ends Buttery Fly Cut = 2.20 mm (0.087 in.).
- One Butterfly End, One Inverted Butterfly End = 2.61 mm (0.103 in.).
12. Install the 2C piston (1) into the retainer/bulkhead (11).
13. Position the 2C Belleville spring (5) onto the 2C piston (2).
14. Position the 2C Belleville spring snap-ring (6) onto the 2C Belleville spring (5).
15. Using Spring Compressor 8249 (2) and a suitable shop press (1), compress the Belleville spring until the snap-ring is engaged with the snap-ring groove in the retainer/bulkhead.
