For General Motors 4T60, 4T60E, and 4T65E Transaxles
While the case does not seal the path of any pressurized oil in the reverse servo of General Motor's 4T60E and 4T65E transaxles, excessive servo wear has been known cause the servo pin to "hang up" in the case. When this happens, the band drags in the forward gears, which destroys the band.
The 4T60-R kit contains all tooling necessary to repair the reverse servo pin bore. It is a Red series kit, and is available as either a Master (pictured) or Sub kit.
