150082017-02-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; EQUIPMENT. "15008 - SERVICE UPDATE. THIS BULLETIN PROVIDES A SERVICE PROCEDURE TO INSTALL TWO BOLTS ONTO THE TRANSFER CASE ADAPTER HOUSING ON CERTAIN VEHICLES EQUIPPED WITH A 2.5L ENGINE (RPO LCV) AND A 6-SPEED AUTOMATIC TRANSMISSION (RPO MYB). THESE VEHICLES MAY BE MISSING TWO LOWER TRANSFER CASE ADAPTER BOLTS. THIS COULD CAUSE INCREASED VIBRATION AT VEHICLE SPEEDS ABOVE 80 MPH (128 KM/H). CAE ANALYSIS SHOWS THAT THERE WILL BE INCREASED STRESS LEVELS TO THE TRANSMISSION HOUSING, BELL HOUSING, AND ADAPTER HOUSING. IF A VEHICLE WITH THIS CONDITION ALSO HAS A SEVERELY IMBALANCED DRIVELINE AND IS OPERATED AT HIGH VEHICLE SPEEDS FOR A LONG PERIOD OF TIME, THESE INCREASED STRESS LEVELS COULD LEAD TO CRACKS IN THE TRANSMISSION HOUSING, BELL HOUSING, AND ADAPTER HOUSING. IF CRACKS OCCUR, THE VEHICLE COULD LEAK TRANSMISSION FLUID. WITH ENOUGH FLUID LOSS, THE “CHECK ENGINE” LIGHT WILL ILLUMINATE. ADDITIONALLY, IF THE ADAPTER HOUSING DEVELOPS A CIRCUMFERENTIAL CRACK, THE VEHICLE COULD SUDDENLY LOSE PROPULSION."

Some customers may comment that the vehicle has reduced acceleration at low speed and/or transmission is slipping from a launch. Technicians may find DTC P0751 set or stored in history. This condition may be caused by the Clutch Select Solenoid Valve 2 (359), located in the lower valve body, sticking in its bore resulting in a 4th gear start. Note: This condition can be very intermittent and difficult to duplicate.
