Control Valve Body: Removal

WARNING: This page is about a different car, the 2002 GMC Sierra and 2002 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using the wiring harness connector remover, disconnect the external wiring harness from the main transmission connector. See Figure .
  2. Remove the oil pan and suction filter. See INTERNAL FILTER REPLACEMENT  under LUBRICATION.
    NOTE: The transmission main connector is actually one end of the internal harness that protrudes through the main housing.
  3. Place a 1 3/16" (30 mm) or 12-point deep socket or box end (2) over the connector (1). Push inward on the socket or wrench to release the retainer "feet" that attach the connector (1) to the main housing. See Figure . Remove the wrench. Push inward on the electrical connector to separate it from the main housing. This allows the internal wiring harness to remain with the control valve assembly as it is removed.
  4. Remove the 2 detent spring bolts (3). Remove the detent spring assembly (2). See Figure .
    NOTE: As the control valve assembly is removed, be careful not to lose the manual selector valve pin or allow the manual selector valve to slide out of the control valve assembly.
  5. Remove 14 bolts at locations marked (1). See Figure . Support the control valve assembly (about 10 pounds) and remove the last bolt marked (1).
  6. Lower the control valve assembly (1) to clear the dowel pins (2) in the main housing. See Figure .
  7. Move the control valve assembly (4) sideways to disengage pin (1) in the manual selector valve (2) from the slot in detent lever (3). See Figure . Remove the control valve assembly (4).
