i bought a car off a mate, we are both tryin to fix it up, while im trying to save for other expenses on it. back it the day, its was running fine until one night he had a full car and tryed to do a burnout, but dumped it to first from neutral while reving it. and ever since that when you accelerate the car starts to shudder. im pretty sure that the trans isnt slipping. so im hoping its the tail shaft or maybe even a bent axle. im not sure. we need to find the problem before we start pulling everything apart. its an auto by the way, and if you drive it like a manual the shudder isnt as bad. e.g. 1,2,D any ideas on what it could possibly be? thanks.
