How many miles does the car have on it? It can be number of things, including the engine and/or transmission mounts you identified, but my first guess would be the differential bushing. On high mileage Vs. both the dual-mass original equipment flywheel and the driveshaft become candidates for driveline snatch.

The car is a 2006 with 70k miles it has the ls7 clutch kit with flywheel from Luke

My vote goes to the rear diff bushing. I replaced mine at 55k miles on my 06 V was night and day with the shifts

Whats the severity of a DIY for a diff bushing?

hmmm you do need a special tool and a friend makes the job easier unless you bench 200+, or use a jack to put the diff back in place. It isn't bad, dropping the exhaust was harder than the job itself, i'd say it's a 3/10.

The hardest part for me was getting the manifold bolts to line up with the rest of the exhaust. If you have the bushing extraction/installation tool, it's not that hard of a job.

Not unless, perhaps, you're an involuntarily severe multi-tasker.

Indeed, jerking while shifting gears sounds like a DIYer. A multi-tasking DIYer.
