I just had my transmission completely rebuilt by aamco... and a new clutch installed, resurfaced flywheel, etc. I know there is supposed to be a "break in" period... but i've driven it for about 130 miles, and whenever i accelerate with some decent force, i get a wierd vibration/sound... it only occurs in the lower gears... Anybody know if i should be terribly worried? Aamco is closed on the weekends so i cant call them, but of course if anything is wrong, i have the aamco 12 mo. warranty....

Thanx!
