Hey, on the car I just bought, when it shifts gears, you can feel the whole tranny move. It moves more the more throttle you give it. Kinda feels like it has a shift kit, but like that the tranny mount is bad. Could this be it, or is there something else that it could be?

 

tranny mount. ½ an hour job to change it.
I just changed my tranny mount because it had torn in to two pieces
