Tremec TCET17805 TKX 5-Speed Manual Transmission

The TREMEC TCET17805 TKX is a 5-speed, rear-wheel-drive manual built for the aftermarket rather than a single factory platform, which is why TREMEC lists it as semi-universal and ships it in its own package rather than bundled with vehicle-specific brackets.

How it shifts and holds up

Multi-cone synchronizers with hybrid synchronizer rings keep shifts smooth across all five forward gears, topping out with a 0.68 overdrive fifth and a 2.56 reverse, and TREMEC builds in oversized gear widths, gaskets at every case flange, and caged needle bearings at each gear position for long-term durability. The ribbed, three-piece aluminum housing keeps weight down while its end-loaded design still fits most transmission tunnels with little or no modification.

Shaft, fluid, and shipping details

26 splines drive the input, handing off to 31 on the output shaft, with a slip-on-style yoke not included. Approved fluids include GM Synchromesh, Pennzoil ATF, non-synthetic Dexron/Mercon ATF, and Mobil 1 ATF. Boxed for shipping, the unit runs roughly nineteen inches deep, thirty-four tall, and fourteen wide, weighing somewhere around fifty pounds with its packaging.

Does it include a shifter? Yes, a shifter ships with the transmission, though the yoke does not.

Is this transmission vehicle-specific? No, TREMEC builds and lists this version as semi-universal for the aftermarket, so confirm your own bellhousing and mounting setup will mate to it.
