This bulletin is being revised to add additional model years. Also, the identification tag color for remanufactured transmissions has changed. Please discard Corporate Bulletin Number 00-07-30-009A (Section 07 -- Transmission/Transaxle).


There may be some confusion about the Goodwrench® transmission assembly program and whether a Goodwrench transmission is new or remanufactured.

It should not be assumed that a Goodwrench transmission is a remanufactured unit.

Goodwrench transmissions for the current model year are new transmission assemblies. A new Goodwrench transmission may be identified by inspecting the transmission stick-on label. The stick-on label will indicate "Manufactured by General Motors" and the identification tag is blue. A remanufactured Goodwrench transmission may be identified by inspecting the transmission stick-on label. The stick-on label will indicate "Remanufactured for General Motors" and the identification tag is black.
