Transmission mount
 

Alright so I bought a torque solutions tranny mount couple months back and finally got around to installing it. Now I'm well aware of that there will be some noise and vibration.

Right off the bat, gears feel much smoother going in and everything feels nice and tight.
Now my only concern is when I'm in gear and decelerating there's a harsh vibration going on. This problem doesn't happen when I throw it in neutral and coast, only while in gear.

Everything is installed properly as it should be and torqued to specs. Has anyone ran.into this problem or is it normal ?

it's very normal

Yea causes a ton of noise and vibration. a lot of people have sold it for this reason.
