Th350 Transkit

The TH350 Transkit from B and M Automotive is a comprehensive transmission rebuild and performance upgrade package designed for hot rodders, restoration specialists, and serious enthusiasts who demand reliable power delivery from their classic and modified vehicles. This kit is specifically tailored for the TH350 transmission model, ensuring compatibility and optimal performance.

Built to address the demands of both stock restorations and high-output engine swaps, this transkit delivers the shift quality, durability, and tuning flexibility that separates a properly assembled transmission from an amateur rebuild. It includes precision-engineered internal components, upgraded friction materials, and calibrated valve body modifications that optimize shift timing and line pressure across the entire RPM band.

Whether you're finalizing a frame-off restoration or upgrading an existing drivetrain, the TH350 Transkit provides everything needed for a professional-grade installation that will handle increased horsepower and torque without compromise. This package consolidates critical wear items—bands, seals, gaskets, and clutch packs—into a single, organized assembly that eliminates guesswork during rebuild and ensures consistent performance characteristics.
