Installation Procedure
WARNING: This page is about a different car, the 2007 GMC Yukon XL and 2007 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
- Install the pressure regulator valve using J 36850 .
- Pre-assemble the following parts:
- The reverse boost valve bushing
- A new reverse boost valve
- A new pressure regulator spring retainer
- The added isolator pressure regulator spring
- The pressure regulator spring
- Install the pre-assembled parts into the pump bore.
- Install the reverse boost valve bushing retainer ring while holding the reverse boost valve bushing in place.
Ensure the retainer ring (2) is in the groove.
- Install the transmission filter. Refer to Automatic Transmission Fluid and Filter Replacement .
- Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Checking .
- Reset the TAP values. Refer to Transmission Adaptive Functions .
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.
