Replacement/Transmission Heat Shield Replacement).
9. Install the exhaust pipe assembly. Refer to Catalytic Converter Replacement (4.2L Engine) (See: Engine, Cooling and Exhaust/Exhaust
System/Catalytic Converter/Service and Repair)Catalytic Converter Replacement (5.3L Engine) ().
10. Install the transmission support. Refer to Transmission Support Replacement (See: Body and Frame/Frame/Cross-Member/Service and
Repair/Transmission Support Replacement).
11. Remove the transmission jack.
12. Lower the vehicle.
13. Fill the transmission to the proper level with DEXRON(R) VI transmission fluid. Refer to Transmission Fluid Check (See: Testing and
Inspection/Component Tests and General Diagnostics/Transmission Fluid Check).
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 engine control module (ECM),
powertrain control module (PCM) or transmission control module (TCM) will need to relearn TAP values. Transmission performance
may be affected as new TAP values are learned.
14. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) (See: Description and Operation/Transmission Adaptive Functions
(TCM)).
