BorgWarner has said it will supply its DualTronic transmission control system for Fiat Powertrain Technologies’ (FPT) first dry dual-clutch transmission.


It says the transmission is one of three variants of the C635 family of six-speed gearboxes with a range of engine torque capacities.


Launching in late 2009, the dry dual-clutch C635 transmission will first be available on the Alfa Romeo MiTo and is expected to expand to a wide range of Fiat, Lancia and Alfa mid-sized C and D segment models beginning in 2010.


“This application expands BorgWarner’s DualTronic controls technology to a dry dual-clutch system for the first time,” said John Sanderson, President and General Manager, BorgWarner Transmission Systems .


The BorgWarner DualTronic control system developed for the dry dual-clutch C635 transmission employs high pressure electro-hydraulic solenoids working in combination with an on-demand electrically driven hydraulic pump to reduce fuel consumption.


This control module is based on solenoid designs engineered and produced by BorgWarner’s facility in Monaco, which has supplied solenoids for Selespeed and Freechoice automated manual transmissions (AMT) and will also produce high pressure solenoids for the automated manual version of the C635 transmission, available in late 2010.
