Wiring Harness: 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. Remove the oil pan and suction filter. See INTERNAL FILTER REPLACEMENT  under LUBRICATION. Disconnect the external wiring harness from the main transmission connector. See Figure .
  2. Use the wiring harness connector remover, if connector is not easily accessible.
    NOTE: The main transmission connector is actually one end of the internal wiring harness that protrudes through the main housing.
  3. Place a 1 3/16" or (30 mm) 12-point deep socket or box end wrench (2) over the main transmission connector (1). See Figure . Push inward on the socket or wrench to release the retaining "feet" that attach the connector (1) to the main housing. Remove the wrench.
  4. Push inward on the electrical connector to separate it from the main housing. Disconnect the internal wiring harness connectors (1) from solenoids "A" through "F" and from the pressure switch assembly. See Figure .
    NOTE: The solenoid retainers for "E" and "D" solenoids also retain tabs on the wiring harness "U" channel.
  5. The solenoids will remain in position even after the solenoid retainers are removed. Remove the solenoid retainers (2) for solenoids "E" and "D". Remove the internal wiring harness from the transmission. See Figure .
