Control Valve Body Removal / Installation

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle re-learns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts either soft or firm and this is a temporary condition and will eventually return to normal operating condition.
  1. Disconnect the negative battery cable.
  2. With the vehicle in NEUTRAL, position it on a hoist. See LIFTING .
    NOTE:
    • If a transmission has been disassembled to replace worn or damaged parts and the valves in the main control valve body stick repeatedly from foreign material, the torque converter must be removed and cleaned by using a mechanically agitated cleaner, such as the torque converter/fluid cooler cleaner.
  3. Remove the oil pan and oil strainer. See AUTOMATIC TRANSMISSION OIL PAN (GASKET AND OIL STRAINER) REMOVAL / INSTALLATION , .
  4. Unclip control valve body wire harness.

    • Lift up on wire harness guide and protector and disengage the retaining pins from the solenoid clamps.
  5. Disconnect the (1) SS1, SS2, SS3 and CCS/SS4 electrical connectors.
  6. Disconnect the (2) torque converter clutch (TCC) solenoid electrical connector.
  7. Disconnect the (3) electronic pressure control (EPC) solenoid electrical connector.
