just driving the car bout 10 minutes ago..I hit the gas hard..and I hear the same noise I experienced not even 3 months ago. I changed the mount then..and it has been fine..is there a possibility that I already blew it again after this short of time? and on a stock Z...this is rediculous

 

quit playing so hard. Believe it or not i thought i heard you could put a few hose clamps or clamp similar to that around the mount and it will help keep them from pulling a part. That way you don't have to go with a poly mount.

 

rksport has a polyurethane mount for 40 bucks..is that my best bet? I think the last one I bought was a peice as crap..is there anything else it could be?

 

Very possible. Did you buy the part from Autozone or is a GM part?
The ploy mounts are a lot strong then the stock ones, but they have a little vibration to them.

 

Ive gone through 2 tranny mounts. This is very common thing. I would suggest a poly. Since I installed it I havent broken the mount in over a year

 

You won,t break a poly mount but it does produce some vibrations.
Mine does it worst at the top of each gear but it smooths out as soon as the TC locks up.

 

Time for a change!
