Just got back from a 200 mile ride on my 2002 TC. Probably did 185 back road twisty beautiful ride, but the 15 mile town driving has got me worried. While driving in town I developed a knock in the trans. Once I got back on the open road it ran like a swiss watch. Do you think the trans just got over heated or something more serious? With the wealth of knowledge on this forum I'm sure someone has seen this before. Thanks guys.
