Inter Lock Pin

The BERT Transmissions Interlock Pin (Part 67) is a precision steel fastener engineered for manual transmission assembly and rebuild applications. This small but critical component functions as a mechanical lock mechanism within Bert transmission housings, preventing unintended gear selector movement and ensuring positive engagement during operation. Fabricated from hardened steel in natural finish, the interlock pin withstands the cyclic loads and vibration inherent in high-performance and racing transmissions where gear selection reliability is non-negotiable.

Measuring 1.45 × 0.3 × 2.5 inches and weighing just 0.01 lbs, this pin integrates seamlessly into Bert transmission shift mechanisms. The interlock pin's role is to create detent friction and prevent accidental cross-gate shifts, a function that becomes especially critical in vehicles operating at high RPM or experiencing sustained lateral acceleration. The steel construction resists wear from repeated shift cycles and maintains dimensional stability under the thermal and mechanical stress typical of race and modified vehicle environments. Proper installation requires understanding transmission shift linkage geometry and detent spring tension—specifications that Bert documentation clarifies for technicians rebuilding or servicing these transmissions.

This interlock pin is designed for transmission builders, race mechanics, and serious enthusiasts rebuilding Bert manual transmissions for street or competition use. Whether you're performing a complete rebuild, replacing worn internals, or assembling a fresh unit for a dedicated track vehicle, this OEM Bert component ensures your shift mechanism functions with the precision and reliability the transmission platform is known for. Stock this pin as part of your transmission service kit or order it individually when replacing damaged or worn pivot fasteners during overhaul.
