Fitment Guidance

This forward sprag assembly is intended for late-design 1995-up GM 4L60E-family transmissions using the matching 29-element forward sprag configuration. It may be relevant to certain 4L60E, 4L65E, and 4L70E transmission rebuilds.

Verify the transmission identification, original forward sprag design, attached gear configuration, hub style, splines, gear teeth, and mating race surfaces before ordering. Do not rely on vehicle year or model alone, as GM transmission configurations can differ by application, model year, and prior repair history.

Repair Information

The forward sprag is a one-way clutch component used within the forward clutch area of the transmission. During rebuild service, inspect the full assembly for race wear, damaged clutch-hub surfaces, gear tooth damage, worn bushings, heat marks, and other evidence of internal transmission failure.

This listing includes a used assembly with the attached gear. The 29-element sprag installed in the assembly is new. The purchaser or installer should inspect the part and all mating transmission components before final assembly.

Installation Guidance

Professional transmission installation is recommended. Confirm correct one-way operation and assembly orientation before installation. Inspect the forward clutch hub, mating races, bushings, planetary components, fluid passages, and related internal parts before reassembly.

Use the manufacturer-specified automatic transmission fluid after service. Lubegard ATF Protectant may be used when compatible with the application and according to its product directions; it does not replace needed mechanical repair.
