Like the title say when I drive I feel vibes when the tranny is in drive, when in 1st, 2nd, or overdrive I dont. Is something about to go out?

 

How many miles? Has it done it since new? "Drive" (or 3rd gear) is the direct drive ratio, so if a component in the transmission is out of balance, 3rd gear is when it will show up.

 

car just turned 34K and I have owned it since it had 12K on it. I have noticed the vibs for a while but I rarley drive in 3rd so I forgot about it for a while. So would a transgo kit fix the problem. Oh and I had the drive shaft replaced under warrenty because it was out of balance. That was about 9 months ago.
