This overdrive sprag is a replacement roller clutch for compatible late-style GM 4L80E and 4L85E transmission overdrive assemblies. It is designed to support proper one-way clutch operation and torque transfer within the overdrive planetary and overrun drum area.

A worn, damaged, or incorrectly matched overdrive sprag can cause internal transmission operation concerns. During overhaul, inspect the roller clutch races, overdrive planetary, overrun drum, related clutch components, and fluid condition before reassembly.

Fitment Verification Required:
Confirm your original unit uses the 3.00-inch OD roller clutch with 0.196-inch rollers. This item is intended for late-style applications and is not interchangeable with earlier 4L80E overdrive sprags that use 0.309-inch rollers.

For a complete transmission fluid service, use Lubegard ATF as appropriate for the vehicle’s specified automatic transmission fluid.
