a. Be careful not to tilt the piston when installing.
b. Be careful not to damage the lip seal.

7. Install the one-way clutch inner race.





(1) Using a press, install the thrust needle bearing to the inner race.
- Use the PULLER assembly (398527700) when removing.

(2) Install four seal rings.
- Apply Vaseline to the groove of the inner race and to the seal ring after installation, so that the seal ring will not expand.





(3) Place the spring retainer CP on the inner race. Install the spring to the recessed portion of the piston. Then tighten eight socket head bolts from the rear side of the transmission case. Be sure to tighten evenly.
Tightening torque: 23-26 Nm (17-20 ft.lb)

8. Install the band servo sub assembly.





9. Press the O.D. servo retainer into position, and secure with a snap ring.
- Perform the following operations with the transmission case set vertically on wooden blocks.





10. Installation of the low reverse brake:
(1) Install two dish plates, driven plates, drive plates, and a retaining plate, and secure with a snap ring.
a. Pay attention to the orientation of the dish plate.
b. Driven plate : 8
c. Drive plate : 8
d. Dish plate : 1





(2) Apply compressed air intermittently to check for operation.
(3) Check the clearance (Selection of retaining plate)
Standard value: 1.1-1.7 mm (0.043-0.067 in)
Allowable limit: 2.7 mm (0.106 in)

NOTE: Before measuring clearance, place the same thickness of shim on both sides to prevent retaining plate from tilting.

11. Install the thrust needle bearing to the inner race.
12. Install the forward clutch drum assembly.
(1) Install carefully while rotating the drum slowly paying special attention not to damage the seal ring.





(2) Installation is complete when the drum recedes 2.5 mm (0.098 in) from the inner race surface.





13. Assemble the overrunning clutch hub.
a. Join the thrust needle bearing and thrust washer with Vaseline, and then install them together.
b. Make sure that the splines are engaged correctly.





14. Install the one-way clutch outer race assembly. Make sure the forward clutch splices are engaged correctly.





15. Assemble the rear internal gear.
(1) Join the thrust needle bearing and thrust washer to the gear with Vaseline, and install the gear while rotating it.
(2) Securely engage the bearing with the dog of the overrunning clutch hub.
- Installation is complete when the snap ring top surface of the forward clutch drum recedes approximately 3.5 mm (0.138 in).





16. Install the rear planetary carrier. Attach the thrust needle bearing to the inside of the carrier with Vaseline. Then install the carrier while rotating slowly.





17. Install the rear sun gear. Install the gear with the oil hole facing up.





18. Install the front planetary carrier. Attach the thrust needle bearings to both sides of the carrier with Vaseline. Install the carrier carefully, while aligning with the splines of the forward clutch drum, and while rotating the pinion.





19. Install the front sun gear. Attach the thrust needle bearing to the gear, and install the gear while turning slowly.





20. Install the high clutch hub. Attach the thrust needle bearing to the hub with Vaseline and install the hub by correctly engaging the splines of the front planetary carrier.





21. Install the high clutch assembly. Correctly engage the high clutch hub and clutch salines.





22. Install the reverse clutch assembly.
- Engage the high clutch outer spline with the reverse clutch spline and the front sun gear with the cut-out portion of the reverse clutch drum correctly when installing





23. Install the brake band assembly.
a. Be careful not to damage the brake band when Installing.
b. Install the strut to the band servo piston stem. Then tighten it temporarily to avoid tilting the band.

24. Adjustment of total end play and reverse clutch end play





(1) Measure the distance from the transmission case mating surface to the recessed portion of the high clutch drum "L", and the distance to the top surface of the reverse clutch drum "M".





(2) Measure the distance from the oil pump housing mating surface to the top surface of the oil pump cover with needle bearing, and to the thrust surface of the reverse clutch.

(3) Equation for calculation
Total end play - C = (L + 0.4) - A
Unit: mm
C: Clearance between concave portion of high clutch and end of clutch drum support
L: Length from case mating surface to concave portion of high clutch
0.4: Gasket thickness
A: Height from housing mating surface to upper surface of clutch drum support

Select suitable bearing race so that clearance C is in the 0.25-0.55 mm (0.0098-0.0217 in) range.

Reverse clutch end play - C = (M + 0.4) - m
Unit: mm
C: Clearance between oil pump housing hose and end of reverse clutch
M: Distance from case mating surface to upper surface of reverse clutch
0.4: Gasket thickness
m: Height from housing mating surface to thrust receiving area of reverse clutch

Select suitable thrust washer so that clearance C is in the 0.55

25. Install the oil pump housing assembly.
(1) After completing end play adjustment, insert the bearing race* in the recess of the high clutch. Attach the thrust washer and thrust needle bearing to the oil pump cover with Vaseline.





(2) After correctly installing the gasket to the case mating surface, carefully install the oil pump housing assembly. Be careful to avoid hitting the drive pinion against the inside of the case.

CAUTION: Be careful not to damage the seal ring.

NOTE: Be sure to use a new casket

(3) Install both parts with dowel pins aligned. Make sure no clearance exists at the mating surface. Any clearance suggests a damaged seal ring.





(4) Secure the housing with two nuts.
Tightening torque: 38-44 Nm (28-33 ft.lb)
