11. Remove the transmission crossmember from the vehicle.
12. Lower the tail section of the transmission slightly.
13. Disconnect the transmission oil cooler pipes from the transmission.
14. Remove the wiring harness clamp bolt (1) attaching the clamp to the transmission.
15. Disconnect the transmission 20-way electrical connector (2).Compress both tabs on the connector and pull straight up; do not pry the connector.
16. Disconnect the vehicle speed sensor electrical connector (3).
17. Support the transmission using a transmission jack.
18. Remove the transmission bolts.
19. Separate the transmission from the engine.
20. Attach the J21366 to the transmission.
21. Lower the transmission from the vehicle.
Installation Procedure
1. Raise the transmission up to the vehicle.
2. Remove the J21366 from the transmission.
3. Align and install the transmission to the engine.
Notice:
Refer to Fastener Notice in Service Precautions.
4. Install the transmission bolts.
Tighten the transmission bolts to 38 Nm (28 ft. lbs.).
5. Connect the vehicle speed sensor electrical connector (3).
6. Connect the 20-way electrical connector (2).
7. Install the wiring harness clamp bolt (1) attaching the clamp to the transmission.
Tighten the wiring harness clamp bolt (1) to 2.5 Nm (22 inch lbs.).
8. Connect the transmission oil cooler pipes to the transmission.
9. Align the torque converter and flywheel mating marks, then install the New transmission torque converter bolts.
Tighten the New transmission torque converter bolts to 65 Nm (48 ft. lbs.).
10. Install the torque converter covers.
11. Install the transmission crossmember support.
12. Install and adjust the selector lever linkage.
13. Remove the transmission jack.
14. Install the propeller shaft.
15. Install the starter motor from the engine.
16. Install the catalytic converter assembly on the vehicle.
17. Remove the jack supporting the rear of the vehicle.
18. Lower the vehicle.
19. Install the transmission fluid filler tube.
20. Notice:
Whenever you remove the transmission for service, you must perform the automatic transmission oil cooler flushing procedure in order to remove the existing fluid which may be contaminated. This will prevent contamination of the new fluid. You must perform the flushing procedure after the installation of the overhauled or replacement transmission.
Flush the transmission oil cooler, oil cooler pipes and the hoses. Refer to Automatic Transmission Oil Cooler Flushing and Flow Test (J45096) Automatic Transmission Oil Cooler Flushing and Flow Test (J35944-A).
21. Connect the battery ground cable to the battery.
22. Fill the transmission to the proper level with DEXRON VI transmission fluid. Refer to Transmission Fluid Checking Procedure.
23. 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.
Reset the TAP values. Refer to Transmission Adaptive Functions.
