just had a new tranny put in and i had to get my u-joints pressed in before i could try the tranny out.

since i cranked the car up there is a horrible vibration. starting from a stop its not too bad but around 50mph+ while giving it gas and as well as my foot being off the gas the car vibrates pretty bad.

could a bad tranny mount cause this? any1 have any ideas?

 

any rear suspension mods done?

 

all stock

 

Did you visually inspect the new work done?

 

Are you running a stock trans. mount or a poly mount?
