Dual-clutch transmission

Eaton's Procision transmission features seven speeds and uses an all-aluminum casing. It is electronically controlled and hydraulically activated. The system changes gear by switching between clutches to engage a pre-selected gear. Synchronizer rings are used to aid gearshifting. Eaton says its optimized design delivers an 8 to 10% or greater fuel economy improvement over a torque converter automatic. The Procision transmission uses a wet clutch system and the transmission needs one type of oil for the entire unit. An oil cooling system is used to help extend operating life. The dual clutch module is completely contained within the transmission casing. Torsional vibrations are controlled using a five-spring damper. This is sealed with the aim of eliminating contamination. New synthetic oil enables oil and filter change intervals of 150,000 mi (240,000 km). Eaton says that the internal sump filter and electrical system do not require maintenance. The transmission control module is mounted on the transmission casing and all wiring is contained within the casing, helping to ensure that wiring is not vulnerable to external damage. The transmission offers a choice of three power takeoff points and these can be activated altogether or individually from the factory, by a dealership or by subsequent owner if not previously activated. Initial production will be aimed at North America, but Procision will be produced for other markets when there is demand. The transmission will be available in North America from July 2015.
