OD Planetary Gear and OD Direct Clutch Assembly (C-0)





Disassembled View

Disassembly





1. Check operation of one-way clutch.
Hold the OD direct clutch drum and turn the input shaft.
The input shaft should turn freely clockwise and should lock counterclockwise.





2. Remove OD direct clutch assembly from OD planetary gear assembly.
3. Then remove thrust bearing with the race from OD direct clutch drum.





4. Check piston stroke of OD direct clutch (C-0).
Place the oil pump onto the torque converter, and then place the OD direct clutch assembly onto the oil pump.





Use a dial indicator, measure the OD direct clutch piston stroke applying and releasing the compressed air (390 - 780 kPa or 57 - 114 psi) as shown.
Piston stroke: 1.85 - 2.15 mm (0.0728 - 0.0846 inch)





5. Remove snap ring from clutch drum.
6. Remove flange, two discs and two plates.





7. Place special tool on the spring retainer and compress the return spring.
Using snap ring pliers, remove the snap ring.
Spring compressor: J-23327-1
8. Remove piston return spring





9. Remove the OD direct clutch piston with O-ring.
^ Place the oil pump onto the torque converter and then place the OD direct clutch onto the oil pump.
^ Holding the OD direct clutch piston by hand, apply compressed air to the oil pump to remove the OD direct clutch piston.
^ Remove the OD direct clutch piston.
10. Remove two O-rings from piston.





11. Remove bearing and race from OD planetary ring gear.





12. Remove snap ring.





13. Remove ring gear flange from OD planetary ring gear.
14. Remove the Race.





15. Remove snap ring, using screwdriver.





16. Remove retaining plate from OD planetary gear.





17. Remove OD one-way clutch with outer race.
18. Remove the thrust washer.

Inspection and Repair





1. Check discs.
Using a micrometer, measure the thickness of the discs.
Minimum thickness: 2.04 mm (0.0803 inch)
If the thickness is less than the minimum, replace the disc.





2. Check piston return spring
Using calipers, measure the free length of the return spring.
Standard length: 15.8 mm (0.622 inch)





3. Check OD direct clutch piston.
Check that the check ball is free by shaking the piston. Check that the valve does not leak.
by applying low-pressure compressed air.





4. Check OD direct clutch drum bushings.
Using a dial indicator, measure the inside diameter of the OD direct clutch drum bushings.
Maximum inside diameter: 27.11 mm (1.0673 inch)
If the inside diameter is greater than the maximum, replace the OD direct clutch drum.





5. Check OD planetary gear bushing.
Using a dial indicator, measure the inside diameter of replace the OD planetary gear bushing.
Maximum inside diameter: 11.27 mm (0.4437 inch)
If the inside diameter is greater than the maximum, replace the OD planetary gear.

Reassembly





1. Install the thrust washer to the OD planetary gear, facing the grooved side upward.





2. Install the one-way clutch into the outer race, with the flanged side of the one-way clutch facing upward.





3. Install OD one-way clutch with outer race to overdrive planetary gear.





4. Install retaining plate, then install snap ring, using a screwdriver.





5. Coat the race with petroleum jelly and install it to the planetary gear.

6. Install ring gear flange to OD planetary ring gear.





7. Install snap ring, using a screwdriver.





8. Coat the race and bearing with petroleum jelly and install them onto the OD planetary ring gear.

9. Coat new O-rings with ATF and install them on the OD direct clutch piston.





10. Being careful not to damage the O-rings, press in the OD direct clutch piston into the clutch drum, using both hands.





11. Install piston return spring.





12. Place special tool on the spring retainer, and compress the return spring.
Spring compressor: J-23327-1
Install the snap ring with snap ring pliers.
Be sure the end gap of the snap ring is not aligned with the spring retainer claw.





13. Install two plates and two discs then install the flange, with the flat side facing downward.





14. Install snap ring.





15. Check piston stroke of OD direct clutch (C-0)
Place the oil pump onto the torque converter, and then place the OD direct clutch assembly onto the oil pump.





Using a dial indicator, measure the OD direct clutch piston stroke by applying and releasing the compressed air (390 - 780 kPa or 57 - 114 psi) as shown.
Piston stroke: 1.85 - 2.15 mm (0.0729 - 0.0847 inch)
If the piston stroke is not within specification, replace the disc and recheck the piston stroke.
If the piston stroke is nonstandard, select another flange.





Flange sizes





16. Coat the assembled bearing and race with petroleum jelly and install it with the race side facing downward.

17. Align the flukes of discs in the direct clutch.
Install the OD direct clutch assembly onto the OD planetary gear.





18. Check operation of one-way clutch
Hold the OD direct clutch drum and turn the input shaft.
The input shaft should turn freely clockwise and should lock counterclockwise.
