Wish I would have done this sooner , hands down the best drivetrain mod. I installed others drive mods before this but this is the one that made a huge difference. The car no longer jerks downshifting or on wot and the over all driving experience is just smoother. My other mods: driveshaft lockdown, rear bushings, crossmember bushings, steel clutch , clutch delete, detent kit, and pitch stop. It could be a combo of all of those however after install of trans mount there was a very noticeable difference, as for NVH it’s not bad at all I had to really listen for it to hear it. Worth every penny. Even though I had to wait almost a month to get it (it was stuck in customs)
