Alright, I have a problem. I am 75 miles from home for a show, and about 3/4 of the way up, the minor vibration I had doing 60-75 mph just suddenly stops. There was no noise associated with it stopping. When I get into town with stop and go driving, it vibrates a hell of alot more than before, but only between lets say 20-45 mph. At cruising speed it seems to be fine without vibrations at all. I had the driveshaft shortened of course for the t5 swap, and it was balanced at that time. Could it be something with the balance of the driveshaft, maybe a u-joint, or was there something going on with the tranny. It seems to shift and drive fine except for this vibration. I haven't been able to get under the car to check anything, and it sits too low to the ground to do it without a jack available. So, I guess, my main question is with the tranny. Has anyone run into anything like this, and if so what was the problem?
