95TransAm_ToM

i had a broken tranny mount so i replaced it with a poly tranny mount now at hard acceleration and high rpms there are vibrations coming from the transmission not the rear end , could it be my u-joints or my drive shaft's not balanced? Or something totally different.

its a 99 Trans am with a 4l60e

i got a lot of vibration after my new rpm trans and a poly mount. fucken sucks. get a bump sound when the trans shifts with the new s60. definitely going to put a rubber one in there if i have to do anything around that area.
