Part 1

When installing/assembling needle bearing, bearing race, snap ring and thrust washer, use the illustration above as a guide to installation procedures and locations.




1. Install parking rod, manual plate, manual plate lock nut, parking brake lever and snap rings.




2. Lubricate and install low and reverse piston into the case.




3. Install piston return spring, thrust washer and one-way clutch inner race.




4. Install hex-head slotted bolts.
Check that return spring is centered on race before tightening.




5. Install steel dished plate first, then steel and friction plates, and, finally, retaining plate and snap-ring.




6. After low and reverse brake has been completely assembled, measure clearance between snap ring and retainer plate. If measurement exceeds specifications adjust by replacing retainer plate with one of a different thickness.

Available retainer plates




7. Check low and reverse brake operation using compressed air.




8. Install governor thrust washer and needle bearing.




9. Install output shaft and governor distributor into case.




10. Install connecting drum with sprag by rotating drum clockwise.




11. Check one-way clutch to see if it operates properly.




12. Install rear internal gear.




13. Install snap-ring on shaft.




14. Secure thrust bearing and thrust washer with vaseline and install rear planetary carrier.




15. Install rear planetary carrier snap ring.
If you have insufficient space to install snap ring into drum groove, pull connecting drum forward as far as possible.

16. Adjust end play as follows:







1. Assemble front internal gear, front planetary carrier and connecting shell. Secure thrust bearing with vase line.




2. Install assembly into transmission case. Check that parts are properly seated before proceeding with measurements.

3. Adjust front end play.




a. Place J34291-1 (bridge), J34291 2 (legs) and J34291-5 (gauging cylinder) on machined surface of transmission case (no gasket). Position bridge legs so short end of legs is down, and adjust legs to fit onto case properly. Allow gauging cylinder to rest on top of thrust washer surface of clutch pack. Now lock gauging cylinder in position with thumbscrew.




b. Remove thrust washer from drum support.
c. Now insert J34290-12 (gauging plunger) into gauging cylinder. Lock gauging plunger by tightening thumbscrew.




d. Place bridge, gauging cylinder and gauging plunger onto machined surface of drum support. Loosen plunger set screw and allow plunger to drop onto drum support thrust washer surface. Now lock gauging cylinder in position with thumbscrew.




e. Use feeler gauge to measure gap between gauging cylinder and shoulder of gauging plunger.

Available Front Clutch Thrust Washer:

f. Use your feeler gauge measurement and following thrust washer chart to select correct washer thickness to give you proper total end play.

4. Adjust total end play.







a. Place J34291-1 (bridge), J34291-2 (legs) and J34291-5 (gauging cylinder) on machined surface of transmission case (no gasket). Position bridge legs so short end of legs is down, and adjust legs to fit onto case properly. Allow gauging cylinder to rest on top of needle bearings in forward clutch. Now lock gauging cylinder in position with thumbscrew.




b. Now insert J34291-13 (gauging plunger) into gauging cylinder. Lock gauging plunger by tightening thumbscrew.
c. Remove oil pump cover bearing race from drum.




d. Place bridge, gauging cylinder, and gauging plunger onto machined surface of drum support. Loosen plunger set screw and allow plunger to rest on top of drum support Now lock plunger thumbscrew.




e. Use feeler gauge to measure gap between gauging cylinder and shoulder of gauging plunger.




f. Use your feeler gauge measurement and following bearing race chart to select correct race to give you proper front end play.

17. Adjust O.D. end play as follows:




1. Adjust O.D. total end play.
a. Remove O.D. bearing race from direct clutch drum support. Leave needle thrust washer in place.




b. Place J34291-1 (bridge.), J34291-2 (legs) and J34291-5 (gauging cylinder) on machined surface of OD. case. Position bridge legs so short end of legs is down (toward drum support), and adjust legs to fit on case properly. Allow gauging cylinder to rest inside direct drum sup- port on top of needle bearing. Now lock gauging cylinder in position with thumbscrew.




c. Put oil pump bearing and O.D. planetary gear assembly on pump.




d. Now insert J34290-13 (gauging plunger) into gauging cylinder. Lock gauging plunger by tightening thumbscrew.




e. Place bridge, gauging cylinder, and gauging plunger on machined surface of oil pump. Loosen plunger set screw and allow plunger to rest on bearing surface of O.D. internal gear. Now lock plunger in position with thumbscrew.




f. Use feeler gauge to measure gap between gauging cylinder and shoulder of gauging plunger.

Available O.D. Bearing Races:

g. Use your feeler gauge measurement and following O.D. bearing race chart to select correct race thickness to give you proper O.D. total end play.

2. Adjust O.D. pack end play.




a. Put thrust needle bearings and O.D. pack on oil pump.




b. Place J34291-1 (bridge), J34291-2 (legs) and J34291-5 (gauging cylinder) on machined surface of oil pump (no gasket). Position bridge legs so that long end of legs is down (to pump) and adjust legs to fit onto oil pump properly. Allow gauging cylinder to rest on top of thrust washer surface of direct clutch drum. Now lock gauging cylinder in position with thumbscrew.
c. Remove O.D. thrust washer from O.D. drum support.




d. Insert J34291-12 (gauging plunger) into gauging cylinder. Lock gauging plunger by tightening thumbscrew.




e. Place bridge, gauging cylinder, and gauging plunger onto machined surface of O.D. case. Loosen plunger set screw and allow plunger to rest on machined thrust washer surface in O.D. case. Now lock plunger thumbscrew.




f. Use feeler gauge to measure gap between gauging cylinder and shoulder of gauging plunger.

Available O.D Thrust Washer:

g. Use your feeler gauge measurement and following thrust washer chart to select correct washer thickness for proper total O.D. pack end play.




18. Install brake band, band strut, and band servo. Lubricate servo O-rings before installing.




19. Install and tighten the retainer bolts.
Loosen piston stem.




20. Tighten piston stem of brake band servo with finger enough to prevent brake band and strut from falling out.
Do not adjust brake band at this time.




21. Apply vaseline to bearing race and thrust washer, then mount them on drum support.




22. Mount drum support gasket � on drum support after coating with vaseline. Apply A.T.F. to O-ring of drum support. Align drum support with O.D. case to transmission case and install.
23. Apply A.T.F. to O-ring of drum support, then install drum support and O.D. case.
Before installing drum support and O.D. case on transmission case, ensure that they have been centered properly. Refer to Component Parts for Drum Support.




24. Temporarily tighten O.D. case with two converter housing securing bolts.
