If you experience the bucking when your letting the clutch out it could mean you have a warped clutch/flywheel. I havent read this thread through though. I admit, i skimmed Just giving my 2 cents.Well, it has nothing to do with a warm engine/trans. Because it actually feels worse and worse the longer i drive.
I had to go pick up somthing the other night, it was about a 100mile trip, through the city, the temp was probably 0 degrees. But anyways, it just seems like as soon as i let go of the clutch to accellerate, it doesnt feel smooth like when its warm out. the car bucks a little.
This goes on for every gear, not just first. And the only way to make it smooth is if i just let the clutch go fast, instead of smooth.
It sucks!, it might be the DBW as well.
