Removal Procedure
  1. Remove the transmission fluid pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement.

    2. Object Number: 795920 Size: SH
  2. Disconnect the electrical connector (1) from the torque converter clutch (TCC) pulse width modulation (PWM) solenoid valve (2).

    3. Object Number: 795835 Size: SH
  3. Using a small suitable tool, remove the TCC PWM solenoid valve retainer from the control valve body.

    4. Object Number: 792782 Size: SH
  4. Remove the TCC PWM solenoid valve (1) from the control valve body.
  5. Remove the O-ring seals (3-4) from the TCC PWM solenoid valve (1), ONLY if the O-rings are cut or worn.

Installation Procedure

    Object Number: 792782 Size: SH
  1. Install new O-ring seals (3-4) to the torque converter clutch (TCC) pulse width modulation (PWM) solenoid valve (1), if the O-rings were previously removed.
  2. Install the TCC PWM solenoid valve (1) into the control valve body.

    3. Object Number: 795835 Size: SH
  3. Install the TCC PWM solenoid valve retainer into the control valve body.

    4. Object Number: 795920 Size: SH
  4. Connect the electrical connector (1) to the TCC PWM solenoid valve (2).
  5. Install the transmission fluid pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement.

    6. 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.
