The TR-6070 is based on the 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.

<span class="mw-page-title-main">Automatic transmission</span> Type of motor vehicle transmission that automatically changes gear ratio as the vehicle moves

An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive the wheels over a wide range of speeds.

<span class="mw-page-title-main">Manual transmission</span> Motor vehicle manual gearbox; stick shift

A manual transmission (MT), also known as manual gearbox, standard transmission, or stick shift, is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch.

The T-56 six speed manual transmission has been used in a wide range of vehicles from General Motors, Dodge, and Ford Motor Company. The transmission was originally designed and built by BorgWarner for the Dodge Viper later being used by GM in 1992 for the generation II and later engines, but from 1998 was built by Tremec, though nothing changed internally. The T-56 has been succeeded by the Tremec TR-6060 transmission in many former T-56 applications, as well as applications requiring greater strength than the T-56 could offer.

<span class="mw-page-title-main">Dual-clutch transmission</span> Type of vehicle transmission

A dual-clutch transmission (DCT) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears.

Shift blocking is a feature of automobile manual transmissions added to improve fuel economy ratings in the Corporate Average Fuel Economy (CAFE) system by preventing a driver from switching from first gear to second or third as would be done normally. A solenoid prevents the shifter from engaging these gears, forcing the driver to shift from first to fourth gear. The solenoid is computer controlled, and will deactivate if the throttle is opened wide enough, or the car reaches speeds above those typical in city driving.
