I know i might get some gruff about this but here it goes. I was reading around and i see everyone has the shudder problem 30-50 mph but the question i have is does it happen imedietly when you start driving?? or does it take a little while like when the fluid gets hotter?? Iv done all the stuff to try to solve mine but it did not help. My car is fine when i first drive it but then it does it. The one other thing i was wondering about is anyone have the shudder vibrate stuff in the back end of the car?? It feels like it travels to the rear of the car and vibrates everything.
