I have a 1.8t with 67,000 miles(auto with tip). I'm not sure how to describe the issue I am having but I will try my best. First of all it seems to be happening more on hot days with the ac on. When driving, especially in traffic with stop and go driving the engine or transmission seems to get ahead of itself and then it slams into gear. If I remember it did this some in previous summers but it seems it has become more regular. Could my transmission be going? Any info will help
