04 mustang 3.9 vibration

[Hobby790]

Hi! So I have an 04 mustang 3.9 5 speed. When I bought the car a couple of weeks ago, it would vibrate when engaging (letting off of) the clutch. It would do this from a stop when pulling out in 1st and reverse, and less violently when upshifting and downshifting. So I figured it was hot spots in the flywheel. So I replaced the clutch kit and flywheel with new OEM parts. Still have the same problem. So today I'm going to check the motor mounts and transmission mounts, and check the u-joints and the throw out bearing and fork, make sure they are in the right place. BTW, clutch kit included throw out bearing, pilot bearing, pressure plate and disc. It's got me baffled, was gonna see if anyone may have had the problem before and got it resolved. Any help appreciated. Thanks

Had a similar problem on a camaro v6 1997. Seemed like an issue with engine mounts. I would say that is the most likely as the transmission mount doesn't really effect twisting of the transmission.
