i keep breaking transmission mounts, they replaced them w/ stock ones again i think that is y. what are some good ones that will handle racing abuse? some kind of polyurithane ones or something? someone help, tired of replacing them.

 

I use the Moroso Steel Motor and Trans Mounts.
Never broken one and vibration is not increased much at all.
Just be sure to use them on both the engine and trans or the stress can crack the trans case.

Check your motor mounts, they sound like theyre broke or weak. unless you have a 700 hp motor, you shouldnt be breaking trans mounts.
