Removal Procedure
- Remove the transmission oil pan and filter. Refer to
Automatic Transmission Fluid and Filter Replacement
.
Important: Do not remove the valve body for the following procedures. Removal of the 1-2 accumulator is necessary only if servicing the pressure control solenoid.
- Remove the 1-2 accumulator if necessary. Refer to
Accumulator Assembly, Spacer Plate, and Gaskets
.
- Disconnect the internal wiring harness electrical connectors from the following components:
• | Transmission fluid pressure switch (1) |
• | 1-2 shift control solenoid (2) |
• | 2-3 shift control solenoid (3) |
• | Pressure control solenoid (4) |
• | Torque converter clutch (TCC) pulse width modulation (PWM) solenoid (5) |
• | 3-2 control solenoid (6) |
- Remove the pressure control solenoid retainer.
- Remove the pressure control solenoid.
- Remove the 1-2 and 2-3 shift solenoid retainers.
- Remove the 1-2 and 2-3 shift solenoids.
- Remove the 3-2 control solenoid retainer.
- Remove the 3-2 control solenoid.
Installation Procedure
- Install the 3-2 control solenoid.
- Install the 3-2 control solenoid retainer.
- Install the 1-2 and 2-3 shift solenoids.
- Install the 1-2 and 2-3 shift solenoid retainers.
Notice: Refer to Fastener Notice in the Preface section.
- Install the pressure control solenoid.
Ensure that the electrical tabs are facing outboard.
- Install the pressure control solenoid retainer and retaining bolt.
Tighten
Tighten the pressure control solenoid retaining bolt to 11 N·m (97 lb in).
- Connect the internal wiring harness electrical connectors to the following components:
• | Transmission fluid pressure switch (1) |
• | 1-2 shift control solenoid (2) |
• | 2-3 shift control solenoid (3) |
• | Pressure control solenoid (4) |
• | 3-2 control solenoid (6) |
- Install the 1-2 accumulator. Refer to
Accumulator Assembly, Spacer Plate, and Gaskets
.
- Install the transmission oil pan and 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 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.
- Reset the TAP values. Refer to
Transmission Adaptive Functions
