A couple days ago my wife spent about 50 minutes in bumper to bumper, stop and go, traffic waiting to pay the toll crossing from Michigan into Ontario. As she paid and was cleared to cross the bridge she noticed the transmission overheat warning light had come on and was yellow. She had to cross the bridge but then stopped and shut off the car for 15 minutes and the light went off and the temp back to normal. She drove for six more hours with no problem. The car has 7k miles on it and I'm assuming this is probably a normal thing for the DCT but it made me wonder just how normal it is or how often it happened to others with this transmission. Also a bit worried about how long it would have been before the light turned red. Thoughts?
