The TREMEC TR-6070 7-Speed Manual Transmission

Corvette Stingray iconA perfect combination of precision performance, ingenious design and brilliant engineering

The Chevrolet Corvette has been an iconic nameplate in the sports car world since its introduction back in 1953. The C7 Corvette, which was introduced in 2014, also brought about the reintroduction of the Stingray name.

This is truly a world-class vehicle. It features new technology, design and manufacturing methods using an aluminum frame and many carbon-fiber body parts. Boasting an estimated 455 horsepower (335 kW) and 460 lb-ft (624 Nm) of torque from the stock 6.2L V8 engine, zero to 60 mph time is in the four-second range.

Standard specifications of the vehicle feature the TREMEC TR-6070 7-speed manual transmission. The transmission offers impressive performance and includes Active Rev Matching, a feature that matches engine and vehicle speed for smooth, quick and precise down shifts – like those performed in track racing. The vehicle software recognizes when the vehicle is decelerating and “blips” the throttle, matching input (engine speed) with output speed (wheel speed) when downshifting to lower gears. Rev Matching replaces the heel-toe driving technique, making a perfect shift every time. This feature can be toggled on and off using the steering wheel paddles.

The transmission is mounted to the rear axle, behind the driver to achieve an almost 50/50 weight distribution for high performance vehicle handling. The engine mounted clutch system is activated by a hydraulic release system and power is transferred through a torque tube/driveshaft arrangement connected to the front of the transmission.

TREMEC achieved a significant milestone in creating a high torque 7-speed transmission that is packaged in a similar space as the TR-6060 6-speed manual transmission found in earlier generation Corvettes.  

The TR-6070 has several ratio options that are based on GM Regular Production Option (RPO) codes for vehicle orders by the dealer from the factory.


Design features of the TR-6070 synchronizers include a combination of double-cone and triple-cone rings, utilizing a hybrid solution on all forward gears.  The hybrid rings are a combination of carbon and sintered bronze cones – providing higher capacity and shift performance. Linear bearings lower the friction of the shift rail movements, making the shifter feel naturally lighter and more direct.

The C7 Corvette has a drive-mode selector with five general settings – Weather, Economy, Touring Sport, and Track – all of which can be further tuned to the driver’s wants. The vehicle uses an advanced clutch set with a dual-mass flywheel to further isolate engine-firing pulses and reduce gear rattle – a source of noise, vibration and harshness (NVH) issues.TREMEC TR-6070 7-speed manual transmission

Other new developments in the TR-6070 include a speed sensor in the rear of the transmission, a new front transmission plate and extension housing, and internal cooling pump to maximize performance. Beaded gaskets are used to improve sealing between the case castings.

The seventh-generation Corvette establishes the benchmark for modern performance cars by using advanced technologies to deliver more miles per gallon and reduce emissions. The triple overdrive transmission helps boost the vehicles highway fuel economy to 29 MPG and 17 MPG in the city.

The new C7 Corvette is truly a wonder of design and improvement over an already fabulous car. TREMEC is proud to be the designated transmission supplier for this epic vehicle. Lighter and faster, with an absolutely gorgeous body design, Corvettes are again raising the standards on the performance vehicle market.
