Plug Shift Shaft

The Winters Transmission Shift Shaft Plug (Part No. 68052) is a precision-engineered component designed for high-performance and competition transmissions where gear engagement reliability demands exacting tolerances. This compact yet critical fastener serves as a protective seal and structural element within Winters gearboxes, commonly found in drag racing, circle track, and off-road competition vehicles.

Whether you're rebuilding a transmission after a season or performing preventive maintenance on a proven power unit, this OEM-equivalent plug ensures proper fluid containment and prevents contamination of internal shift mechanisms. Manufactured to Winters' strict dimensional specifications, the shift shaft plug measures 0.25 x 0.25 x 0.5 inches and is crafted to maintain precise fitment within the transmission housing.

This small but essential component prevents cross-contamination between separate fluid circuits and protects delicate shift shaft bearings from moisture and particulate intrusion—factors that directly impact transmission longevity under sustained high-RPM operation and aggressive shift events typical of competition driving. Mechanics and transmission specialists rebuilding Winters boxes for street or strip use will find this OEM plug essential for assembly integrity and leak prevention.
