We have designed the clutches to do this, so it's not placing any undue strain or wear on the clutch."īecause the engine and transmission are permanently linked, the truck won't free roll down a hill. "Customers can select the speed they want for creep mode and we control the clutch engagement accordingly.
"The creep speed is controlled by clutch slippage, not engine idle speed," says Systems engineer, Tony Stasik.

Drivers can shuttle back and forth between forward and reverse without coming to a stop, and based on a brief test drive of the transmission, there's no hesitation when shifting between forward and reverse. Forward and Reverse creep speeds are independently adjustable to allow a customized lower speed in reverse. Regardless of the application, the Procision transmission features several performance enhancements not currently available with traditional automatic transmissions.Ĭreep Mode allows controlled low-speed parking lot and loading dock driving without applying the accelerator. “It is easy to tailor, which is key for fleet owners looking to put trucks on the road that best meet their business needs.” “Our customers had direct input on the features they want in a medium-duty transmission, and because of this real-world input, the Eaton Procision is smart from the word go,” said Joe Semaan, commercial vehicle segment director, Eaton’s Vehicle Group. While the base transmission remains the same, it can be electronically programmed to meet the specific demands of dozens of different applications, from a typical pickup and delivery operation or rental truck fleet to tow trucks and school buses. The electronic controls are mounted on the transmission to reduce wiring and connector complexity, and the entire unit is fully sealed to eliminate contamination. A five-spring damper is used to control torsional vibrations.
The dual clutch module is fully contained within the transmission, hydraulically controlled and oil cooled for extended life. It's a closed-loop control system that significantly reduces slip and steady state losses associated with torque converter automatic transmissions.” From that gear, the next gear is preselected and the torque path shifts back to the first clutch, and so on. The shift is executed by transferring the torque path from one clutch and input shaft to the other, and that transfer of power is seamless. While the transmission is in a particular gear, the next gear path is preselected in the unused clutch and input shaft. "Think of input shaft A linked to clutch A, and input shaft B linked to clutch B. There are two input shafts and two clutches, explained Jeff Carpenter, engineering manager for the Procision transmission. But the benefits of maintaining a constant gear mesh throughout the shifting sequence improve fuel economy significantly, especially in stop and go situations.
To the driver, it feels like a torque-convertor equipped automatic transmission.

Eaton says the torque path to the drive wheels is not interrupted by the gear change, so the driver never feels any lag in power as he or she would with a traditional manual transmission - even an automated manual. The key to the Procision transmission is the dual-clutch shifting technology.
