Universal Megashifter

The B and M Automotive Universal Megashifter (Model 80690) is a floor-mount automatic transmission shifter engineered for custom hot rods, street machines, and performance-modified vehicles seeking a clean, modern shifter solution. This universal shifter delivers the forward/reverse pattern common to most automatic transmissions while eliminating cable bind and inconsistent shift feel that plague aged or compromised factory shifter assemblies.

At 9.15 lbs with compact overall dimensions (12 x 7 x 12.7 inches), the Megashifter fits tight engine compartments and custom floorpan installations without requiring extensive modification. The included 5-foot cable provides sufficient routing length to navigate frame rails, tunnel work, and firewall passages common in retrofit applications. Hardware package is complete, eliminating sourcing delays on installation day. The universal mounting pattern accepts a wide range of transmission tailhousing and floor-mounted bracket configurations, making it compatible with various powerplant and transmission combinations found in street rod, muscle car, and custom truck applications.

Builders and restorers choose the Megashifter when factory shifter mechanisms are unavailable, damaged, or incompatible with modern driveline swaps. The forward/reverse detent geometry provides positive engagement and eliminates accidental neutral drop during acceleration. This shifter suits Chevrolet, Ford, Chrysler, and independent engine platforms running three-speed, four-speed, and overdrive automatic transmissions. Installation requires basic mechanical skills, standard hand tools, and cable routing planning to match the specific vehicle's interior and powertrain layout.
