ONE-WAY CLUTCH
Disassembly, Inspection & Reassembly
1. Record direction of rotation one-way clutch locks and turns. Remove snap ring and pull out planetary carrier from one-way clutch inner
race. See
Fig. 8
. Check for worn or damaged parts. Bushing wear on one-way clutch must not exceed 5.120" (130.06 mm).
2. Check clearance between pinion gears and washers in planetary carrier. If clearance exceeds .031" (.80 mm), replace planetary carrier.
Reverse disassembly procedure to reassemble. Install one-way clutch in inner race and ensure that it will turn in one direction
(clockwise) only.
REAR CLUTCH
Disassembly
1. Remove large snap ring. Lift out retaining plate, clutch plates, and dished plate. See
Fig. 21
. Using appropriate compressor, compress
rear clutch spring retainer to remove small snap ring, spring retainer, and clutch return springs.
2. Place front clutch on oil pump and rear clutch hub on top of front clutch. Apply air pressure to rear clutch oil passage to remove piston.
See
Fig. 16
. Remove and discard piston seal rings.
Inspection
Inspect for wear or damage. Ensure return spring free length is 1.031-1.071" (26.20-27.20 mm).
Reassembly
1. Install seal rings on piston and install in clutch drum by applying even pressure on perimeter of piston and rotate piston slowly. Install
return springs and spring retainer. Press spring retainer. Install snap ring. Note direction of dished plate and install. Install driven and
drive plates, retainer plate and snap ring. See
Fig. 21
.
2. Ensure clearance between snap ring and retainer plate is .031-.039" (.80-1.00 mm). If clearance is not within specification, select correct
retaining plate. Retaining plates are available in thicknesses .189" (4.80 mm) to .244" (6.20 mm) in .20 mm increments.
3. Check rear clutch operation by placing forward clutch on oil pump and then rear clutch. Apply compressed air (70 psi maximum) to
rear clutch oil passage and check operation. See
Fig. 16
.

REAR CLUTCH HUB
Disassembly, Inspection & Reassembly
Remove snap ring and separate hub from internal gear. Check for worn or damaged snap ring or gear and replace as needed. Reverse
disassembly procedure to reassemble hub.
VALVE BODY
Disassembly
1. Remove instruction control valve. Remove oil strainer retaining bolts and oil strainer. Remove upper-to-lower valve body retaining bolts.
Separate valve bodies, separator plate and sub-body. DO NOT lose check balls and springs or orifice valve and spring. See
Fig. 22
.
2. Remove, clean and install each valve individually as needed. See
Fig. 22
. Lubricate moving parts with ATF. Ensure all valves move
(snap) freely. If valve sticks in its bore and cannot be freed, valve body must be replaced. DO NOT attempt to hone valve bores or
polish valves.
3. Inspect the valve springs for signs of damage or deformation. Measure valve spring free length and diameter. Refer to the
VALVE
NOTE:
Remove and clean one valve at a time to avoid incorrect installation. If any valves, valve springs, or
valve bodies are damaged, the entire valve body assembly must be replaced.
BODY SPRING DIMENSIONS
. Reassemble components in reverse order of disassembly.

VALVE BODY SPRING DIMENSIONS
Reassembly
1. To reassemble, reverse disassembly procedure. Coat all parts with clean transmission fluid. DO NOT force valves into position. Ensure
orifice check valve, check ball and springs are located correctly.
2. Place separator plate on lower valve body and hold with clamps. Install upper valve body and bolt into place. Tighten upper valve body
to lower valve body. See
Fig. 23
.

TRANSAXLE CASE
Inspection
Inspect case for cracks and stripped threads. Inspect gasket surfaces and mating surfaces for burrs. Check vent for obstructions, and check all
fluid passages for obstructions and leakage. Inspect case bushing for scores. Check all parking linkage parts for wear or damage.
TRANSAXLE REASSEMBLY
OUTPUT SHAFT BEARING PRELOAD
1. Position output shaft into torque converter housing. Position output shaft outer bearing race in recessed end of Gauge Tool (T87C-
770002DJ). Place gauge tool over output shaft. See
Fig. 24
.
2. Ensure gauge tool is completely threaded together so that no gap is present. Position spacer collars and assemble output bearing and
idler support to converter housing using supplied bolts and washers of tool set. See
Fig. 24
. Tighten bolts to 14-19 ft. lbs. (26 N.m).
NOTE:
Handle all parts carefully to avoid damaging bearings and mating surfaces. Lubricate all parts with
clean ATF. Use petroleum jelly on gaskets, thrust washers and needle bearings to retain them in place.
Soak all friction discs in ATF for at least 15 minutes. Use all new gaskets and seals, and tighten bolts
evenly.
NOTE:
For identification and position of thrust bearings and washers, see
Fig. 27
