If your driveshaft is out of balance I would expect the vibration to get worse the faster it turns and not get better, but maybe someone has a had a different experience. Does the vibration still happen if you shift into 3rd and really low RPM?
Pretty low, 2000rpm, can't say that I shift into 3rd any lower than that in this slug. As the speed increases it gets a little better, still a constant vibe that shakes the rear view mirror to where I can't see out of it.
Seems strange that no matter what RPM or speed I go in 1st or 2nd I don't feel it, shift to 3rd foot on the gas instantly there.
