Inside Lever

The Brinn transmission inside lever (MPN 73003) is a precision shift linkage component engineered for manual transmission systems requiring direct, responsive gear selection. This inside lever serves as the critical connection between your shifter mechanism and transmission, delivering the mechanical advantage and accuracy needed for smooth, positive engagement across all gears. Built for high-performance and street applications where shift quality directly impacts drivability, the inside lever is essential for anyone upgrading to a Brinn transmission or restoring OEM shift geometry on a custom build.

Constructed from durable steel in natural finish, this inside lever is manufactured to exact tolerances for reliable operation under repeated shifting cycles. The lever's geometry is optimized to translate shifter input into precise transmission actuation, minimizing lost motion and dead zones that compromise shift feel. Hardware is included, allowing for immediate installation without sourcing additional fasteners. At just 0.14 lbs, the compact design (2 x 0.7 x 3.95 inches) integrates seamlessly into existing transmission housings while maintaining structural rigidity required for consistent performance across a wide range of engine power levels and driving conditions.

Transmission builders, engine swap specialists, and serious enthusiasts value this lever for its role in achieving factory-tight shift quality on custom and modified vehicles. Whether you're converting to a Brinn transmission in a swap application or replacing a worn shift lever on an existing installation, this component ensures your gear selection remains crisp and reliable. Proper installation requires mechanical knowledge of transmission linkage geometry; work with a qualified technician if unfamiliar with shift lever adjustment and binding diagnostics to maximize shift performance and eliminate transmission strain.
