When I launch and shift hard from 1-2, I hear a dull but loud knocking sound that is very concise coming from the passenger side of the engine bay. It also happens when I am cruising in fifth at low engine RPM and quickly give it gas. When I hear this sound, the car also jolts rather violently.

I revved my engine at the throttle body and it doesn't seem to be moving more than half an inch or so.

Is it my tranny mount?

yea i sometimes get a thud like that too, sounds like mine is coming from behind tho. and i just got a new driveshaft and carriers so its not that knocking. but when im in 5th and give it gas i get the random like thud noise. it cant be play in the driveline cause everything is really tightened up, ive checked.

Your tranny mount rubber was fine when i saw it, but you did have one stripped out bolt where the mount bolts to the tranny. The rubber COULD have broken, though. Most likely it would be the lower motor mounts, though.
