c. Fasten tool to transmission using two servo cover bolts and torque to 18ft. lbs.

d. Ensure gauge pin moves freely in tool and pin bore.

e. Apply 25 ft. lbs. of torque to the nut on gauge.




f. Select correct pin, per figure.




18. Remove six bolts, extension housing assembly and O-ring, per figure.




19. Remove nut, pin, detent lever and actuator assembly, per figure.

20. Remove parking pawl bracket and spring.

21. Remove parking pawl shaft hole plug with a screw extractor.

22. Remove parking pawl shaft retainer, shaft and pawl.

23. Remove seal and manual shaft.

24. Check front end play as follows:




a. Install dial indicator tool No. J-8001 or equivalent to transmission, per figure.

b. Eliminate slack by pressing down on turbine shaft and with pry bar tool No. J-28585 or equivalent press up on output carrier, then pull up with 3-5 lbs. of force on turbine shaft to eliminate any clearance between snap ring and overdrive carrier.

c. Index dial indicator against end of turbine shaft and set dial to zero.

d. Pull out turbine shaft while holding output carrier up, then increase lifting force to approximately 20 ft. lbs. and read endplay. Proper endplay is .O04-.022 inch.




e. If endplay is not as specified refer to thrust washer chart, per figure, for correct thrust washer sizes.

25. Check rear endplay as follows:




a. Install dial indicator tool No. J-8O01 or equivalent to transmission, per figure.

b. Push in on output shaft to take up any slack.

c. Place dial indicator against output shaft and set dial to zero.

d. Move output shaft in and out noting amount of endplay. Proper endplay is .005 - .O25 inch.




e. If endplay is not as specified refer to thrust washer chart, per figure, for correct thrust washer sizes.




26. Remove turbine shaft O-ring, per figure.

27. Remove seven pump mounting bolts and attach puller tool No. J-37789 or equivalent, then remove pump assembly from transmission.




28. Remove pump gasket and selective thrust washer, per figure.
