I have had the same issue twice with my duel dry clutch transmission. Both times it has made it so I can not move and I was stuck in the middle of the road with the service transmission message on. Both times I was not able to move even after restarting the car. The first time the dealership said there was nothing wrong and the second time the problem was a leaking hydraulic line to the clutch. The first issue happened at around 5k miles and the second time around 7k miles. I am curious if other have had this problem or heard of this problem.
