NEW low reverse sprag for the 1993-up 4L60E, 4L65E transmissions

BorgWarner 28571AM

If your transmission has high miles it would be a good idea to change this during your rebuild

The 4L60E and its variants were in production from 1992-2013 and can be identified by the square 16 bolt oil pan and 4 forward gears. 1992-1993 are cross-over years, so your vehicle could have the earlier non-electronic transmission instead.  If unsure of your model, the 4L60E can be differentiated by looking at the wire plug going into the transmission. The non-electric shift will have a square wire plug with 2-4 wires. The 4L60E will have a round plug with 11 wires.

The 4L60-E was found in the full range of General Motors vehicles including, Buick, Cadillac, Chevrolet, GMC, Hummer, Isuzu, Oldsmobile, Pontiac, and SAAB.

These transmissions can be found in the following vehicles; however you should double check your application with the 16 bolt pan count. It is common for similar vehicles to have multiple transmission options available from the factory.
