Car shakes -- need help!

[coliphage]

Hi,

My car shakes like hell when in gear (D and R). The steering wheel shakes like I am doing some kind of hand massage. It's much better if the car is in P or N. I think this must be related to the engine/transmission mounts. I can see that the front mount is pretty much worn. I am wondering if other mounts need to be replaced as well.

Which mount(s) most likely to cause such shaking, i.e., a lot of shaking when in gear, much better in N and P?
Thanks

My car is 99 Eclipse auto 420A NT with 114k

Any mount being toast will result in the shaking. Inspect them all and replace accordingly.

That tranny mount under the battery tray can be a big issue. I've got the poly mounts in all of the motor mounts and my car shakes already. Well it didn't help that the shop who was warrantying a clutch job put the tranny mount in upside down. Which caused it to shake even more.

Someone ought to tell this guy about how he can fill blown motor/tranny mounts to save some time and get better traction off the line.
