I think my mounts are shot. Not sure though. How can you tell? My car drives great in town. No issues. When I take it out and go wot from 45mph, the car downshifts and has a flutter sound. Maybe the y pipe? If I stay on it, the car will get better the faster I go. It's just from 45 to 90 that has this issue.

being that you have an a4, have a friend power brake the car in drive and reverse. You should be able to see a difference between the two mounts.

You mean look at the engine while a friend does this? Check to see how much it moves?

Best way you need lift up your Camaro up appx 2 ft at front. Go undercar and check on trans. mount.
If you have strong arms then do lift up-down and shake on trans mount, if there bad loose. You would know that mount rubber wear out and time to replace new one.

So anyhthing over 40 you would get a niose? Mine does it around 45. I'll check the tranny mount in the morning. Give myself an extra work out. I'm a body builder! I was going to replace the mounts this winter anyways. Now I'm sure I'll have to. Thanks for the pics and info.
