[NC-V]

I just installed the insert and motor mounts. No need to remove the mount, takes 15 min or less.
-Get the exhaust pipes out of your way (removed the midpipes on my corsa).
-Put a jack under the back of the trans with a block of wood inbetween.
-Jack up the back of the trans until the mount hits its uptravel limiter.
-Lube up the insert
-Shove it in the gap in the mount (this will take some force. I got it started then bumped it in with a dead blow hammer)
-Drop jack
-Re-install midpipes
-Enjoy no extra vibes, less trans movement and a non-sunk trans mount

I am quite pleased with the whole package (motor and trans mounts)

I tried the exact same thing earlier with poor results. I think his transmission mount is softer / more worn than mine is (24k miles on my 06).

I have 65k on my 05. By no means am I saying it slid right in, but if you jack it up all the way to the stop, lube it, get the front lip/edge started into the mount then you can beat it in with a dead blow hammer. When you are putting it in watch the slot in the insert and make sure the edges aren't getting caught on the center post of the mount.

When I installed the insert I did a custom short throw similar to the pisnuoff (sp?) version, and upgraded all shifter bushings. This combo made my shifts more solid and have less play than the TR6060 shifters in the 5th gen camaros.

xbladr: pop the shifter handle/surround off and make sure the shifter is hitting or binding on anything in the console (like the big chunk of foam or rubber grommet) from boost in height from the insert. try removing that stuff and see if you can shift into 2nd and 4th . If not in there, jack up the car and have someone try to put it in second and forth while you're watching from underneath to see what is binding.

Sounds exactly like the linkage is hitting the driveshaft yoke. I'm pretty sure you welded a 1" diameter pipe on the bottom which lowers the linkage just about 1". My shifters use to hit with the UUC mount because it is 3/8" taller than the stock mount. I reduced the length of my insert and inverted the pivot ball housing which brought the linkage up about 3/8" and now there are no issues with my shifters and the UUC mount combo. If you don't want to or can't modify the shifter differently you can insert a shim plate between the metal pivot retainer and the linkage bracket and notch out the plastic retaining plate inside the console. This will raise the entire assembly into the console.

This definitely makes sense. When I modified my shifter, I didn't use 1" pipe, The material I used only extends about 3/4" lower than the original shifter bottom and with the height boost from the insert, it is tight down there. Let us know what you find!
