I noticed today that while operating my vehicle my engine jerks whenever I accelerate. For example, when I come to a red light or stop sign, and pause for a few seconds, as soon as I take my foot off the brake and acelerate my vehicles speed up to about 20 miles per hr. the engine jerks back; it sounds like a loud thud. But once it is in gear I don't have this issue anymore. It only occurs once I bring my vehicle to a complete stop. What exactly coulod this be, and is it something major or minor in terms of being repaired? This is my only vehicle.....Please help!!!! Thanks, dsallen83

Do you have a check eng light on?
COMMENT by dsallen83 on September 04, 2009
My check engine light has never came on. I always make sure to stay on top of the upkeep of the maintenance of the vehicle so this kind of boggles me. Also its not every day that this occurs; it might happen maybe once or twice a month, but if its something that I can get fixed before the problem spirals out of control, I want to do so.

Maybe a motor mount then? The problem would happen with almost each shift in a manual, but maybe only on the 1-2 shift on an auto if you drive it nice...

Was wondering if you ever got this fixed? I have been having the same problem in my truck. It feels like a hard shift between 1st & 2nd gear I had the tranny rebuilt when 2nd gear started slipping (not sure if this was a side effect of the thudding or seperate issue) it seemed to work for a while and now I'm back to replacing the tranny again.
