Xi Transmission mount

I am curious if anyone has found a decent replacement for the xi transmission mount? I know the xi one is pretty soft to begin with. Is it best just to replace with oem?
I have seen some old threads of guys filling them with liquid poly to make them more solid.
Not looking to add any nvh, just notice my transmission feeling a little sloppy and shaky in lower gears.
Thanks

So there are not transmission mounts like you might find on a rwd car. You would be replacing the transfer case mount which I'm not sure anyone makes an upgraded mount for the xi.

It's a PITA to change. I have no doubt that the T-case manufacturer has a custom made insert for pushing those things in.

My old one came out relatively easily, but it was not fun finding a way to press a new one in.

Yes, at the dealer we have special press tools to install the transfer case mount.

LOTS of soapy water makes it much easier. Never use silicone or oil/grease to install as the bushing can slip out after install.

Thanks all for the input. I assumed replacing oem was the only option.
My car is slammed and I don't have access to a lift. So I will have a shop do this. I figured that bushing is probably getting worn + the with the extra hp, it's probably moving more than it should.
Are there any others under there that contribute or just the one on the transfer case?
Mine is a 2010xi with 90k Miles.

Twisted Tuning makes an aluminum insert which essentially turns the factory mount into a solid one. If this is your daily driver, this probably isn't a good choice. I'm running Twisted Tunings solid transfer case mount insert and 034 Motorsport filled engine mounts but I drive my car maybe 2000-3000 miles a year if that. There is noticeable increase in NVH at idle. I've tried raising idle a bit to compensate which helps, but there is still vibration at idle unless its held above 1k rpms. Shifting feel is much improved though and it definitely removed a lot of slop in my drivetrain.

Your best bet is to fill the OEM mount with some filler material. If you search on here its been done.

Found a thread on here somewhere a while ago. I bought poly mix to mix 95a I think It comes too. Was gonna buy another t case mount and poly fill the spaces of the rubber mount to stiffen it up. Never got around too it lol but I have The poly. Ordered from UK and got to queens NY faster than shit does from California.

It does not.
Have you ever had the transmission and transfer case serviced ? Are you using xhp?

I used window weld to fill a new bushing when I put my car back together. It works well with no noticeable vibration inside the car. Worked great up until I blew my transfer case a few days ago. Launchy launch made it go boomy boom.
