Reverse Clutch: Reassembly
- Prior to reassembly, ensure check ball in inner piston seal is free. Install NEW oil seal on piston. Coat seals and sealing surface in clutch drum with petroleum jelly.
- Install piston into clutch drum using Inner and Outer Seal Protectors (T80L-77403-B and A) to prevent damaging seals. Seals used on reverse clutch piston are square cut; direction of installation is not important.
- Install thrust ring and return spring. Compress return spring and install waved snap ring with points facing downward. Install apply plate into clutch drum with dished side facing piston. Install clutch pack and retaining snap ring.
- Using a feeler gauge, measure clearance between clutch pack snap ring and pressure plate while pushing down on pressure plate. Ensure clearance is .030-.056" (.76-1.42 mm) for 3.8L EFI engine (3 friction plates) and .040-.075" (1.02-1.91 mm) for all other models (4 friction plates).
- If clearance is not within specification, selective snap rings are available in various sizes. See FORWARD & REVERSE CLUTCH SNAP RINGS
. Install correct size snap ring and recheck clearance.
- With reverse clutch reassembly completed, check clutch operation using compressed air. Ensure clutch is heard and felt to apply smoothly and without leakage. Install No. 2 thrust washer or No. 2 needle bearing.
