  1. Remove the main control valve body. For additional information, refer to MAIN CONTROL VALVE BODY .
  2. NOTE: If the tool is not available, extreme care must be taken. Spring pressure will force overdrive servo piston assembly out of case. Case bore damage may result from trying to pry on overdrive servo internal retaining ring.
