This is a complete TREMEC T56 Magnum 6-speed manual transmission package, ready for installation with flywheel, clutch, driveshaft, and bolt kit included. The Magnum is TREMEC’s aftermarket evolution of the TR-6060 architecture, engineered far beyond the original T-56.
It carries a robust 700 lb-ft torque rating, making it suitable for high-output engines producing roughly 600–800+ horsepower in stock form (and more with professional builds). Stronger internals deliver the durability: wider face-width laser-welded gears, a reinforced one-piece countershaft, larger bearings, 26-spline input and 31-spline output shafts, plus triple-cone synchronizers on the lower gears for crisp, high-rpm shifts and long service life under street or track abuse.
The dual-overdrive gearing keeps highway RPMs low for comfortable cruising and better efficiency, while the short-throw shifter and dual speedometer provisions (mechanical and electronic) add versatility.
