Will be replacing the motor mounts on my 96C2 and figured the transmission mount is likely in bad shape as well (haven't confirm condition). In researching the topic, I learned that the transmission mount on a C2 can't be replaced without removing the transmission, something most do when replacing the clutch. Since my clutch is fine, I found this interesting interim solution - transmission mount insert. Has anyone installed this? Results?

Is there a functional reason why you are changing the mounts?
If not consider just replacing the motor mounts.

The insert and RS motor mount will tighten the feel of car for sure. Especially shift feel.

1. Try FD motorsports or Rennline as a source for the actual mount. The issue is getting the old one out when the transmission is in the car. I just did this when had the tranny out to I do a clutch job. It was a PITA getting the factory one out with the thing out of the car. This would be near impossible if not purely torture in the car! I honestly would wait until you need a new clutch. Is the mount showing cracks? You can lift the rubber 'covers'-if still in place over the side of the mount. Visually inspect to see if there are obvious cracks of the mount. In retrospect the factory one I took out wasn't exactly in perfect shape; however, since "I was in there" I just went ahead and installed a HD version from Rennline. It could have gone a few more years thought. What was also failing; and had a lot of flex was when I removed it, was the lower carrier mount that bolts to rear tranny brace. That was definitely worn out and had a lot of flex. I found this:

It was easier to cut the small, outside metal sleeve and air chisel the thing out and lightly press in the new poly bushing. You could just try this approach and see how that improves on the flex if this is what you think is happening. All these things I mentioned above-including doing a 'refresh/rebuild' of my rubber shift coupling/old crappy designed from the 70's part, improved the shifting feel and smoothness. This is why guys do FD motorsports 'goldenrod' upgrade which is likely happening for me in the next year or two. Wasting your time doing the actual mount until you get the trans out. Seriously don't do it.

Stay away from semi solid trans mount unless you want constant "coffee can of bolts rattling" sound in your car gears 2-5 when windows are up.

For those that have a trans mount insert coupled with stiffer motor mounts and a golden rod or equivalent, do you notice increased vibration in shifter?

I recently installed the Powerflex insert in the nose mount, and the complete replacement bushing in the longitudinal mount. I'm running WEVO black motor mounts, and an RS style solid shift rod. At exactly 4000 RPM I get a pretty good vibration in the shifter that causes the **** to rattle driving me nuts. I also notice increased vibration near redline but it's not enough to make the gear **** rattle.

Curious as to others experience with these stiffer mounts.

I don't have the transmission mounts, but everything else. I don't have any vibration on the shifter.

Maybe it's your car telling you to push harder to open the Varioram😁

RS mount is nice. If you have ANY kind of a shop this can be swapped in about 20 minutes. 10x easier than changing a wheel bearing but principle the same.
