This bulletin is being revised to cancel this process. Please discard Corporate Bulletin Number 04-06-01-034B (Section 06 - Engine/Propulsion System).


Due to the many changes in the process and the low volume of components effected, this bulletin is no longer applicable. Dealers should be going through the PQC for exchange programs for both OEM and Goodwrench® engines, transmission and transfer cases. The Warranty Parts Center (WPC) will continue to issue part return requests for units desired for analysis.

Thank you for your continued support and cooperation with these types of programs. With your help we have been able to continuously improve the quality of our products.
