Transmission mount???

[yellowstang1994]

Hi guys, I have a question thats been concerning me for a while. Say i'm cruising about 70 or 80mph in 5th gear, like on an interstate. If I let off the gas you can feel the transmission like the whole shifter shift back, and if I give it a little bit to continue cruising you can feel the whole transmission shift back. Lately a few noises been coming too when I turn corners and at idle at red lights my shifter is pretty shaky. Could this be a sign that the transmission mount isn't doing too good?

More than likely, the tranny mount is toast or the motor mounts are.

Hmm, and I just happen to have a brand new, never used energy suspension poly tranny mount in my shop. What are the odds?
