SERVICE INFORMATION
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.
