Claim:
1. A diagnostic method of determining clutch failure of a dual clutch transmission (DCT), comprising: comparing, by a controller, a wheel torque of a vehicle with a driving load torque of the vehicle; confirming, by the controller, whether or not the vehicle is driving, if, as a result of the comparing step, the wheel torque is greater than the driving load torque; releasing, by the controller, a gear engaged with a non-drive shaft, if, as a result of the confirming step, the vehicle is in a stopped state; reconfirming, by the controller, whether or not the vehicle is driving, after the releasing step; and judging, by the controller, that a transmission clutch of the non-drive shaft fails, if, as a result of the reconfirming step, the vehicle is driving.
