ISSUE:

A “rattling” noise in the converter housing area when the torque converter clutch is not engaged may occur on some vehicles. This may be caused by impact between the converter piston and cover spline teeth internal to the cover.

ACTION:

Replace the torque converter. The revised torque converter incorporates a new piston and damper design which reduces the possibility of impact between the clutch piston and cover spline teeth. Refer to the following Service Procedure for details.

NOTE:DO NOT USE THIS CONVERTER TO FIX OTHER CONVERTER ISSUES. THIS CONVERTER IS SPECIFICALLY FOR REPAIR OF 1998 AND 1999 DIESEL RATTLE ISSUES AS MENTIONED IN THIS TSB.

SERVICE PROCEDURE

  1. Run self test and repair and diagnose any Diagnostic Trouble Codes (DTCs) present before continuing.
  2. If rattling is still present, place the transmission gear selector lever in Park.

  4. Cycle the torque converter clutch on and off a few times by applying and removing the ground to Pin 54.
