I bought a TKO 600 from Classic Chevy a year ago and it came with a rubber transmission mount. I remember questioning the guy about it and why he didn't supply a urethane one. I have now forgot but I would like to get the consensus out there for which is the best to run. I am doing a frame off and will be replacing the body mounts and front end bushings with urethane. Any feed back is appreciated.

Any use of poly bushings is just boy-racer stuff that has no benefit on the street. JMHO.

Poly bushings definitely have their place and benefits but not sure I'd agree the tranny mount is one of them. I used the rubber on my TKO conversion and think it's fine. I'm aware that some people who have used the poly mount noted some shifter vibration as a result.

When I did mine I was told for a Tranny mount use rubber it absorbs vibration where poly won't. I used rubber. I don't know for a fact it is true but it makes sence to me.
