I am trying to get some other ideas of what could be wrong with my car. Today I was driving and I start off in first gear and I notice my shifter wobbeling enough to feel it in the car and also into second. After second gear it goes away. My first thought would be that the tranny mount is bad but I tested the mount by getting into the gas and hit boost and the shifter did not rise up. Any other ideas of what could be wrong?

 

I had an awesome shifter wobble around 11mph when I first put my car together. Weak tranny bushing combined with out of balance driveshaft. Went to a steel one-piece and it was 100% cured.

 

When I bought the car about 7K ago the drive shaft was already replaced with a new one. Anything else it could be. I would say it starts right around 11mph but it goes away the faster I go.

 

It's the center bearing on your driveshaft.

 

I have the same thing going on with my car. I have Epsteins old steel 1pc. driveshaft. im thinking its a bad mount.

 

inspect the drive shaft/ output shaft. a good way to check is up on the lift with the car on and somebody in it to put it in gear. That wobble is what they all did to me before I snapped them in half launching.

 

would it make more sense that it is the u joint if it feels worse when going around a turn?

 

Is it the car shaking or just the shifter? If its just the shifter, I would second the bearing analysis, or you lost a weight on the driveshaft. If it is speed related and not engine RPM related you might want to check tire balance, or if you have a snapped belt in a tire (though that is usually a road feel rather than a shifter)
