Main Control Valve Body: Installation

    NOTE: Before installing the mechatronic assembly into the transmission case, verify presence and correct orientation of the thermal bypass valve, pump adapter seal and center support seals. Also note that one or more of the center support seals may have remained in the mechatronic assembly during removal and should be installed into the transmission case at this time.
  1. Verify the 4 rubber feed tubes for the center support are in place.
