Download Product Data Sheet

The 6DCT250 Dual Clutch Transmission (DCT) uses two separate wet clutches for odd and even gears in synchromesh. The gears are controlled hydraulically by an Electronic Control Unit which senses gear positioning and shifting.

The 6-speed DCT is designed for handling engine torque capacities between 220 Nm and 270 Nm and is most suitable on sedans and crossover vehicles.
