Inside the Tremec TR6070 7-Speed Manual Transmission

Last month we looked at the new C7 generation of Chevrolet Corvette, which brings the famous “Stingray” name back into use. GM has invested tremendous amounts of labor and capital to create a real world-class new model, which will be the first to use the new Tremec TR6070 seven-speed manual transmission. The new Stingray’s advanced computer controls will enable the driver to tune the vehicle to a number of driving modes, and Tremec did a really first-class design to provide seven speeds in a package that is only slightly different in size from the previous TR6060.

The New 7-Speed Tremec TR6070 Manual Transmission

This is truly a world-class vehicle. It features new technology, design and manufacturing methods that go way beyond the familiar C5 and C6 Corvettes. These cars have come a long way from the older fiberglass models, using an aluminum space frame and many carbon-fiber body parts. GM has invested a fortune in development and design in a totally new LT1 aluminum-block engine (Figure 3) that produces 450 horsepower and 450 lb.-ft. of torque from the 6.2-liter displacement. Zero-to-60-mph times are in the four-second range, and this is from the stock motor. Higher-performance versions of the new LT1 will be released for the top-of-the-line Corvette models. The most-striking feature of these vehicles is a seven-speed manual transmission, the TR6070 (figures 4 and 5).


Every technician who rebuilds transmissions has failures, which we call comebacks. We get the failed or improperly working unit back, diagnose the cause and make it right.

The entire exercise we go through on a daily basis making repairs is based on the same set of facts: We have to first diagnose the problem, understand the cause of the failure, correct that cause and then certify that the unit is working correctly and deliver the product.

Tremec’s New 6060 Six-Speed

The T56 six-speed transmission has been around for many years now. Originally designed by BorgWarner for the GM F-bodies (Camaro/Firebird), the design has been refined since Tremec bought the BorgWarner manual-transmission business. The T56 is now the six-speed of choice for the Ford Mustang, Chevrolet C5 and C6 Corvettes, Pontiac GTO, Cadillac CTS-V, Dodge Viper and Sidewinder, and Aston Martin Vanquish.
