The newest aftermarket offering from TREMEC is the ultimate performance 6-speed manual transaxle, creating new possibilities for custom car and truck builders. It enables true mid-engine configurations with exceptional on-track performance—ideal for drivers who want the control of shifting their own gears.
Building upon decades of manual transmission experience and leveraging insights from developing the TR-9080 DCT transaxle system for the Chevrolet C8 Corvette, TREMEC set out to create a simplified yet robust manual transaxle. The result? A transmission that helps car builders achieve optimal weight balance and superior handling in a package that is ideal for mid-engine builds and custom rear wheel drive vehicles.
To start, TREMEC designed the transmission to utilize the TR-9080 DCT mounting points and a similar case profile. This allows builders to use already available factory Corvette components for easier installation. The aluminum case design achieves the right balance between strength and weight to handle heavy torque loads. The side-mounted cable shift mechanism provides precise, responsive gear changes.
Inside the TREMEC manual transaxle are 6 forward gears plus Reverse. The gears are designed with helical angles and cut to for maximum torque handling capability while minimizing gear noise. This gives the TREMEC manual-shifting transaxle an estimated input torque rating of 800 ft-lbs of torque, 1,000 horsepower and an impressive maximum engine RPM capability of 8,600. The integrated mechanical limited slip differential provides superior traction under power, enhanced cornering and consistent handling.
ABOVE: The gear ratios in this TREMEC aftermarket transaxle are different from a traditional manual transmission, because a transaxle combines the function (and overall gearing) of the transmission and the axle. After thorough research the ratios were chosen to make the new transaxle compatible with the widest array of engines/power outputs and RPM ranges as possible. The result is a transaxle that can be used in a variety of builds and engine combinations.
The new TREMEC 6-speed manual transaxle brings ultimate performance engineering to the custom vehicle market with exceptional strength, balance, and drivability in mid-engine configurations. TREMEC has made it easier than ever for builders to create high-performance, driver-focused vehicles.
