Symptoms of bad transmission mount/bushing?
So today on my home from work I started to notice my X's seems more jumpy.
I will be at a complete stop and when I take off normally my car lunges slightly. (Like a car with a bad motor mount, that little jerk/lunge when you blip the throttle)
This happens when I blip the throttle to 1500 and let off the clutch. It lunges right when the clutch hits its engagement point.
I had a friend look at the side with the hood opened. I took off normally and he said that the motor moved from back to front about 1/4 of an inch. (Front bumper to rear bumper)
I am guessing its the top transmission mount and possibly the one in the back of the engine.
Any thoughts?
Update:
A few weeks after I noticed this, a bolt from the rear transmission sheared off from backing out and having the stress of my ****ty shifting

on stock mounts mine used to move up to a good 1/2 inch.
have you made any changes to the car lately?

Actually figured out what is happening. I got really worried when I drove it and when I blip my throttle in 2nd/3rd gear at 30ish MPH it had a metal clanking noise.
Brought it to a shop and found out that my rear engine mount/ torque dampener is no longer connected to the transmission/transfer case. A bolt is missing on the mount that connects to the transmission/transfer case.
Just ordered a set of Boomba front and rear mounts. Hopefully the threading in the transmission isn't stripped.

Got the car at the shop right now.
Basically the top side bolt is missing and the bottom side completely sheared off the head of the bolt.
So the rear mount is no longer connected to the transmission.
Car is having the transmission removed and having boomba torque dampeners installed.

I am guessing the top screw vibrated off and then when the top screw fell off the bottom one took all the strain.
Got the car back yesterday with both Boomba front and rear mounts put in.
Its vibrates like crazy below 1500 RPM. I plan on removing the front ones.

I bought the car with modifications. (Cat back w/ HFC, ETS 3" FMIC w/ full ETS piping, AMS Intake, ACT 6 Puck)
