Updated Tremec 6-speed for gen-4 F-body cars


American Powertrain reports the availability of a new Tremec TR-6060/Magnum-F 6-speed transmission designed for fourth-generation Chevrolet Camaros and Pontiac Firebirds, the GM F-body cousins.

The new gearbox is designed to replace the T-56 Magnum, the company said.

“When the T-56 Magnum was released in 2009, the only options for shifter location was far forward or far back, greatly impacting options for quality replacement parts,” according to American Powertrain. “Tremec recognized the need and utilizing their TR-6060/Magnum architecture, designed the Magnum-F 6-speed to meet shifter location requirements and as a bolt-in unit for LS-1 powered ’98-02 F-bodies, as well as third-generation F-bodies, LT-1-powered fourth-gens, LS-swapped late models of all varieties, and sport compact applications such as A80 Supras, FD RX07s, and more.

“Made from 100 percent brand-new OEM quality parts and designed to match the quality of today’s OEM muscle and sports cars, the Magnum-F features increased face-width on all gears, a robust combination of double and triple cone synchronizers, enhanced webbing in the main case, and provisions for a cooler circuit. 

“The shifter is an isolator-type unit, like that found on the Magnum XL. The shifter reduces in-cabin noise and vibrations while at the same time providing the precise and communicative shift feel that all Magnums are known for.”

The new gearbox comes with a 12-moth/12,000-mile warranty.
