A method is provided to control an engine braking operation of a vehicle provided with a dual clutch transmission. The dual clutch transmission is adapted to be set into different gear-combinations, each including an active gear selection through which torque can be transmitted, and a passive gear selection through which no torque can be transmitted. In a pre-set number of gear-combinations, the first input shaft and the main shaft have a synchronised rotation. When an engine braking operation is performed when the transmission is set in one of the pre-set number of gear-combinations modifying said engine braking operation such that a damaging load upon said spigot bearing is reduced.
