TREMEC TCET17805 TKX 5-Speed Manual Transmission, a 5-speed RWD manual transmission developed solely for the aftermarket. For the development of the new transmission, Tremec engineers took a forward-looking approach to finding the best and most efficient solution. This included universal packaging, excellent shifting performance, and extreme durability. The end result is superior shift-ability with smooth shifts at high RPMs through the use of multi-cone synchronizers and hybrid synchronizer rings. At the same time, noise, vibration and harshness (NVH) performance is optimized with a gear layout to best control stress levels, while providing structural stiffness with a ribbed, 3-piece aluminum housing. Durability is further optimized with oversized gear widths, gaskets at all flanges and caged needle bearings in all gear positions. Whether restoring or upgrading a classic muscle car or a 1930s-era roadster coupe, the new Tremec TKX 5-speed RWD manual transmission delivers a top-quality drivetrain solution.
