Main Control - Valve Body: Removal

    NOTE: When the battery is disconnected or a new battery installed, certain transmission operating parameters can be lost. The powertrain control module (PCM) must relearn these parameters. During this learning process, you may experience slightly firm shifts, delayed, or early shifts. This operation is considered normal and will not affect the function of the transmission. Normal operation will return once these parameters are stored by the PCM.
  1. Disconnect the battery ground cable.
  2. Raise and support the vehicle.
  3. Drain the transmission fluid.
