Begin the control and Shift Solenoid service or repair process by removing the transmission oil pan with filter while keeping the Valve Body intact unless servicing the pressure control solenoid requires removal of the 1-2 accumulator. The internal wiring harness electrical connectors of the transmission fluid pressure switch , 1-2 shift control solenoid , 2-3 shift control solenoid , pressure control solenoid , tcc pwm solenoid , and 3-2 control solenoid should be disconnected. You should start by taking off the pressure control solenoid retainer followed by the pressure control solenoid then proceed with removing the retainers and solenoids for both 1-2 and 2-3 shifts before completing with the 3-2 control solenoid retainer and solenoid. The 3-2 control solenoid installation must start followed by the retainer and then install the 1-2 and 2-3 shift solenoids with their respective retainers. The pressure control solenoid installation requires correct placement of electrical tabs facing outward before securing the solenoid retainer with its retaining bolt tightened to 11 nm (97 inch lbs.). Attach the internal wiring harness electrical connectors onto the transmission fluid pressure switch and the 1-2 shift control solenoid , 2-3 shift control solenoid , pressure control solenoid , tcc pwm solenoid and 3-2 control solenoid . The 1-2 accumulator and transmission oil pan and filter should be reinstalled during the completion of the procedure.
