C-6 Ford Transpak

The B and M AUTOMOTIVE C-6 Ford Transpak automatic transmission shift kit is purpose-built for C6 transmission applications spanning 1967–1991 Ford vehicles. This shift kit addresses the core need for improved transmission response, smoother gear engagement, and enhanced shift quality in classic and vintage Ford powerplants. Whether you're restoring a high-performance muscle car, upgrading a daily driver, or fine-tuning a specialized build, the Transpak delivers measurable improvements in shift feel and drivability without requiring complete transmission replacement.

The C-6 Transpak works by recalibrating internal hydraulic pressure curves and shift timing within the transmission's valve body assembly, resulting in crisper, more responsive shifts across all gears. This engineering adjustment reduces shift hesitation and improves throttle-response correlation—critical factors for drivers seeking predictable transmission behavior under both cruising and acceleration loads. The compact, efficient design integrates seamlessly into the existing transmission structure, weighing just 0.93 lbs, and fits within a footprint of 11.15 x 2.5 x 11.5 inches, making it a bolt-in enhancement that respects original factory packaging.

Enthusiasts, restoration shops, and transmission specialists rely on the Transpak for vehicles requiring reliable shift performance in vintage and modified C6 applications. Installation is suited for users with intermediate mechanical experience or professional transmission technicians; the kit requires transmission pan removal and access to the valve body. Compatibility is confirmed for all C6 transmissions fitted to Ford vehicles from 1967 through 1991, including Mustangs, F-Series trucks, and full-size sedans. Proper installation ensures years of responsive, smooth shifting without compromising transmission durability or longevity.
