Tremec TR-6070 transmission

The TREMEC TR-6070 seven-speed RWD manual transmission features seven forward speeds and one reverse speed.[1] It is manufactured by TREMEC Corporation (formerly Transmission Technologies Corporation).

The TR-6070 is based on the well-respected TREMEC TR-6060 six-speed transmission. A triple overdrive gear was added to improve fuel economy and lower emissions. Incorporated in the TR-6070 is a Gear Absolute Position (GAP) sensor. The technology provides a signal from the transmission to the engine controller, inferring the real-time position of the shift selector. With this information, the engine RPM can be controlled to match the next gear selection - which enhances drivability.

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.
