I few words about the Creative Steel mount. It appears to be good quality in its construction. The polyurethane is softer, it gives a little when I push on it hard with my fingernail, the Revshift I couldn't make an indention. This is logical as the CS mount is 40 hardness and the Revshift is 80. The holes properly aligned with the transmission and the studs on the bottom were straight, aligned easily in the support and had plenty of length.
PLEASE NOTE: I am not saying the Revshift is a poor product or inferior construction! I am completely satisfied with their motor mounts and am considering using some of their bushings.
I installed the the transmission mount and tested it out. The quality of the shifting is still good and it goes into reverse easily. There are no new or noticeable vibrations, similar to the revshift once it "broke in."
The biggest difference is in the sound. There is no more spinning sound from the transmission or gear clicking sounds as I mentioned in my earlier post. The car is much quieter throughout the RPM range, though not back to the Cadillac quiet with the original mount. I can hear the radio better at highway speeds and don't have any reverberating or droning sounds.
The important thing is that, for my use, it is quiet enough. I think I had realistic expectations. I did not expect to obtain stock sound levels, but rather reduce the noise to a level tolerable to me. If this was a pure play car or a track car these would not have been issues for me. The CS mount gave me a good blend of accurate shifting and low noise/vibration levels.
Hope this helps anyone debating the two and what they are using it for!
