I can replicate this by pushing half way down on the gas and then fully down 60mph @ 2.5K. It will make a wobble sound like 3 times. At first I thought it was the clutch because I first heard it when shifting into 5th at 3K then I started to test it and it seems like it is something else. Pmohr believes it too be the transmission mount. IT defiantly makes sense. I need to see if anyone else had this issue. It doesn't seem to be a motor mount. There is not hard slams or a big shift of weight as if a mount is shot. IT just makes a hobble sound. Really annoying. Mounts are $50 bucks and I am getting a clutch done soon, so I want to do it all at once but $50 bucks is tough bones to spend along with the clutch so I want to make sure it is it.

Also, any way to test out Mounts on a standard car? It seems really hard. lol. Back in the autos you just do a simple brake stand. Not this time.
