The dual clutch transaxle has seven forward gears and one reverse gear. Both clutch operation and gear changes take place on a fully automatic basis, providing the driver with shifting comfort and vehicle dynamics of the highest level.

An overview of the main features of the dual clutch transaxle: 

• Compact transaxle housing
• A cooling module with integrated pressure fluid filter located on the dual clutch transaxle
• Two sub transaxles, each with multidisk clutch
• Internal and hollow shaft, two output shafts
• A pinion differential integrated in the transaxle housing
• Multi-cone synchronization (3 cones) for transferring high frictional forces during acceleration or during braking of the idler gears during gear changes (1st-3rd gear), dual-cone synchronization (4th-7th gear), single-cone synchronization (reverse gear)
• A wet, hydraulically operated dual clutch
• A shared transaxle fluid circuit (hydraulic control and lubrication of gear set) with one mechanical and one integrated electric oil pump
• A transmission control system with control and shift valves, sensors and actuators
• Electrohydraulically operated park pawl with an electrically actuated engagement device

Advantages of the dual clutch transaxle 

• Short shift times
• Dynamic driving and gearshifting
• Compact design
• Integration of all transaxle relevant hydraulic, mechanical and electrical components
• Maximum comfort through smooth shift operations
• High level of efficiency
