700 LB-FT




Our world-class transmission bulks up

If you’re on the hunt for a heavy-duty transmission able to withstand an unbelievable torque capacity—700 lb-ft to be exact—while still providing crisp shifts, check out the all-new Chevrolet Performance T56 Super Magnum six-speed manual transmission. Simply put, no other Chevrolet Performance manual transmission offers as much combined strength, versatility, and control. Designed for custom, LS retro-fit installations, the T56 Super Magnum is a beefed-up version of the high-performance TR6060 transmission you’ll find in the Camaro ZL1. 


Larger components, including thicker gears and output shaft, provide greater strength. You’ll also find a more conventional slip-yoke design plus a 40-tooth reluctor ring designed for the electronic vehicle speed sensors used with Chevrolet Performance controllers.


The T56 Super Magnum can accommodate three shifter positions and includes a two-position shifter plate, shifter handle, and Chevrolet Performance logo ball-type shifter knob. Combining brute strength with precision engineering, the T56 is the perfect choice for cruisers and track racers alike.
