DISASSEMBLY

Exploded View Of Reverse High Clutch:

1. Remove pressure plate retainer ring, then the plate pack.
2. Inspect steel clutch plates and clutch lining plates for wear, damage, or effects of overheating, replacing entire set if necessary.

NOTE: If new plates are to be used, immerse them in transmission fluid for 30 minutes before assembly.

Clutch Spring And Compression Spring Retainer Replacement:

3. Using clutch spring compressor tool No. T65L-77515-A or equivalent, compress clutch compression springs, remove retaining ring, and carefully release pressure on spring, then remove spring and compression spring retainer.

Removing Reverse/High Clutch Piston Or Air Testing Assembled Reverse/High Clutch:

4. Apply no more than 20 psi air pressure to blow out clutch piston as shown in the Direct Clutch (reverse/high) Piston Removal Or Clutch Assembly Air Test image, using finger to close off opposite hole.

ASSEMBLY
1. Install new seal rings on clutch piston.
2. Carefully install clutch piston into clutch body.
3. Install compression spring and spring retainer, compress springs using clutch spring compressor and install retaining ring, as shown in the Clutch Spring And Compression Spring Retainer Replacement image.
4. Install clutch plates beginning with a steel plate, then alternate friction and steel plates.
5. Install pressure plate and secure with retaining ring.
6. Using feeler gauge, check clearance between retaining ring and pressure plate, pushing downward on plates while checking clearance.
7. If clearance is not 0.051-0.079 inch, install corrective selective retaining ring. Retaining rings are available in thicknesses of 0.0539, 0.0681, 0.0819, and 0.0961 inch.
