Installation Procedure
1. Install the J21366 onto the transmission bell housing to retain the torque converter.
2. Raise the transmission into place and remove the J21366 from the transmission.





3. Slide the transmission straight onto the locating pins while lining up the marks on the flywheel and the torque converter made during removal. The torque converter must be flush onto the flywheel and rotate freely by hand.

4. Install nuts, studs and/or bolts securing the transmission to the engine.
Tighten the studs and/or bolts to 50 Nm (37 ft. lbs.).

Notice: Refer to Fastener Notice in Service Precautions.






5. Install the flywheel to torque converter bolts. Use care not to drop the bolts into the bell housing.
Tighten the bolts to 60 Nm (44 ft. lbs.).
6. Install the torque converter access plug.
7. Remove the safety chain from the transmission.





8. Install the bolts (2, 3) that secure the fuel line brackets to the left side of the transmission.
^ Tighten bolt (3) to 10 Nm (89 inch lbs.).
^ Tighten bolt (2) to 45 Nm (33 ft. lbs.).





9. Connect the main electrical connector to the transmission.
10. Connect the park/neutral position switch connector.





11. Connect the transmission vent hose (2) to the transmission.
12. Install the transmission heat shield.





13. Install the range selector cable end to the transmission range selector ball stud (6) and the bracket (1).
14. Raise the transmission to the normal installed height.





15. Install the catalytic converter assembly.





16. Install the transmission mount.





17. Install the transmission support.
18. Remove the transmission jack.
19. Install the fuel tank shield if equipped.
20. If equipped with 4WD install the transfer case.
21. If equipped with 2WD install the rear propeller shaft.





22. Flush the transmission oil cooler and cooling lines at this time, if necessary.
23. Connect the transmission oil cooler lines (4) to the transmission.
24. Lower the vehicle.





25. Install the filler tube to the stud (1) on the right side of the engine.
26. Install the filler tube nut (2).
Tighten the nut to 10 Nm (7 ft. lbs.).
27. Connect the battery.
28. Fill the transmission to the proper level with DEXRON(r) VI transmission fluid and check for leaks.

29. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM). Transmission Adaptive Functions (TCM)

Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

30. Road test the vehicle and check for proper operation.
