For 1990-2009 cars

### Removal Procedure

1. Remove the transmission fluid pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement.
2. Disconnect the electrical connector (2) from the pressure control solenoid (1).
3. Using a small suitable tool, remove the pressure control solenoid retainer from the control valve body.
4. Remove the pressure control solenoid (1) from the control valve body.
5. Remove the O-ring seals (3-4) from the pressure control solenoid (1), ONLY if the O-rings are cut or worn.

### Installation Procedure

1. Install new O-ring seals (3-4) to the pressure control solenoid (1), if the O-rings were previously removed.
2. Install the pressure control solenoid (1) into the control valve body.
3. Install the pressure control solenoid retainer into the control valve body.
4. Connect the electrical connector (2) to the pressure control solenoid (1).
5. Install the transmission fluid pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement.

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 or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
6. Reset the TAP values. Refer to Transmission Adaptive Functions.
