ISSUE:

A “ticking” noise on initial startup with shift selector in “P” or “N” position may occur on some vehicles. This may be caused by the overdrive clutch steel separator plate(s) impacting against the case internal spline.

ACTION:

Replace the specified transmission components per the following Service Procedure.

NOTE:THE TICKING NOISE TYPICALLY IS ONLY PRESENT DURING INITIAL STARTUP AFTER THE VEHICLE HAS SOAKED LONG ENOUGH FOR THE TRANSMISSION FLUID TEMPERATURE TO REACH NEAR THE AMBIENT TEMPERATURE. THIS NOISE MAY BE HEARD INTERMITTENTLY DURING NORMAL OPERATING TEMPERATURES IN OTHER GEAR RANGES.

SERVICE PROCEDURE

  1. Verify vehicle’s build date (Job #1 built through 6/11/98).
  2. Allow vehicle to soak long enough (possibly overnight) that the transmission fluid temperature is near the ambient temperature. Perform initial cold startup.
  3. Verify ticking noise with the transmission shift selector in “P” (Park) and “N” (Neutral).
  4. When ticking noise is confirmed, refer to the Transmission Hardware Application Chart to update transmission hardware as indicated by vehicle/engine application.

    NOTE:FOLLOW ALL OF THE NORMAL SERVICE PROCEDURE AS OUTLINED IN THE APPROPRIATE WORKSHOP MANUAL.

    NOTE:THE BUILD DATE LISTED MAY VARY SLIGHTLY FOR SOME VEHICLE APPLICATIONS. WHEN SERVICE IS REQUIRED ON A VEHICLE WITH THIS TICK CONCERN, IT IS RECOMMENDED THAT THE TRANSMISSION BE DISASSEMBLED DOWN TO AND INCLUDING THE COAST CLUTCH PRIOR TO PART ORDERING OR PURCHASE. THIS WILL ALLOW VERIFICATION OF THE CORRECT PARTS REQUIRED.

    INSPECT THE COAST CLUTCH WHEN REMOVED. IF THE COAST CLUTCH CYLINDER IS THE NEW DESIGN STAMPED, WELDED STEEL USE THE -BA LEVEL OVERDRIVE PLATES (REFER TO THE APPLICATION CHART). IF THE COAST CLUTCH CYLINDER IS THE PREVIOUS E4OD CAST IRON DESIGN USE THE -CA LEVEL OVERDRIVE PLATES AND ANY OTHER ASSOCIATED PARTS RECOMMENDED IN THE TRANSMISSION HARDWARE APPLICATION CHART.
