There is not specifically a shift pressure control solenoid. There is a line pressure control solenoid, and several shift solenoids, all of which are in the control valve body. It does not show a specific solenoid replacement procedure for any of the solenoids, just a general control valve body replacement procedure. It involves going through the left front wheel well area to remove the side cover. The literature portion is included.
