Description

The TREMEC TKX is the latest in a line of very successful 5-speed RWD manual transmissions and has been 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 aluminium 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.

Particular attention was made by TREMEC during the design of the TKX to ensure that the case size was keep to an absolute minimum.  This was done with the co-operation of the TREMEC Elite dealers who had much experience in installing the transmissions in a wide variety of vehicles.  The result is a compact, high rpm shifting transmission able to handle high performance engines.

• Designed for multiple applications with little to no floor pan modifications
• Compact, end-loaded design provides the perfect solution for custom builds
• Outstanding shift-ability at high RPMs (up to 7500) thanks to the multi-cone synchronizers and hybrid synchro rings
• 600 pound-foot (lb.-ft.) of torque capacity
• Choice of ratios with overdrive to reduce engine wear and fuel consumption for comfortable roadway driving

The transmissions are produced in two main variations with different length input shaft and mounting positions typically for Ford and GM applications – although many bellhousings that are made may install either of these onto different engine families.  Our Roadcraft bellhousings often use the longer input (Ford) transmission to install onto GM engines as it allows more varied clutches and release systems to be used.  The input shaft on all transmissions is made for the GM 1 1/8” 26 spline clutch.  The only TKX transmission that does not is the TCET18086 that uses the Ford 1 1/16” 10 spline.

This transmission has GM 26 spline input shaft and the following ratios, 1^st 2.87,   2^nd 1.89,   3^rd 1.28,   4^th 1.00,   5^th 0.68,   Reverse 2.56
