polyeurothane mounts??
I just replaced my broken tranny mount with a urothane (Energy Suspension) mount and mann this is harsh!! I feel every vibration and loud as a log truck. Is this normal??? I might switch back to a rubber mount??

it's a auto. It vibrates the most under acceleration, but as soon as you let off then it's noisy. It's like I bolted it directly to the chassis. I was going to replace the engine mounts also but I don't know now???

Tried it on both of my 4th gens, ended up taking it off and swapping for a standard LS1 mount.
The ride was too harsh for a DD with a chassis-mounted torque arm; I just replace em as I break em.

There's something else wrong if that's happening. I'd say motor mounts too are toast. I put that same mount in my TPI car after the trans mount was obliterated (trans hitting tunnel) and I never experienced anything like that.

Anymore, I think the dealerships only offer the LS1 mount anyhow.
It looks like Advance Auto still sells both.
LS1 Mount
LT1 Mount

FYI, I started a thread on rubber vs poly trans mounts in the auto trans forum, might have some useful info:
