For General Motors  4T60E & 4T65E Transaxles

Green Series

Kit Picture

Apply oil for the Forward band in General Motor's 4T60E and 4T65E transaxles is routed to the rear of the servo piston through the hollow servo pin.  This arrangement requires the pin to seal  in the case.  So when the case wears, apply oil  leaks out into the case. 

The 4T60-F kit contains tooling necessary to repair the Forward servo pin bore in both 4T60E and 4T65E transaxles.  We save your case by reaming out the case and installing a brass bushing that has proven to wear considerably better than the stock aluminum case.  The 4T60-F is a GREEN series kit that is currently only available as a master kit (pictured).
