4EAT Anti-Wobble Transmission Mount Bushing
The RalliTEK Transmission Mount Insert Bushing for the 4EAT Transmissions is designed to install directly into your factory Subaru transmission mount to reduce excess wobble or drivetrain movement caused by soft or aging OEM rubber. By firming up the mount, this insert delivers noticeably improved shift feel, faster response, and a more connected driving experience.
Features
- Improved shift feel and drivetrain response
- Reduces unwanted transmission movement
- Installs into the factory one-piece transmission mount
Insert Options
- Soft (Street): Ideal for daily-driven vehicles with minimal increase in NVH
-
Hard (Race): Designed for track-focused use; will increase NVH (noise, vibration, and harshness). The hard/race insert can be used on street-driven cars, but expect increased drivetrain noise and vibration.
Note
- Automatic transmission vehicles only
- Does not work with two-piece transmission mounts found on some Subaru models
Built for drivers who want sharper response and better drivetrain control—without replacing the entire mount.

Highly recommend this Transmission Mount Insert Bushing, easily installed this on a 2015 Subaru Crosstrek with heavy vibrations on acceleration and now the vehicle has zero vibrations and even feels more solid to drive!
Could be placebo, But I personally like the feel now. I believe it lessened/removed the slop/jerk from the CVT Torque fake "shifts."
The hard insert was pretty frustrating to install, but after 15 min of pushing and using a bar clamp tool, I got it in. Just be patient and use the lube included!
If you have a table vice, USE IT, makes it 10x easier than pushing by hand.
My Directions:
Remove the Rallitek Transmission Skid Plate -> Remove plate -> Remove OEM Mount -> Install insert -> Reinstall all parts -> Torque everything down
I will buy another one fur sure!! Will this fit my 2008 Subaru Legacy 3.0 H6 with a 5EAT Transmission? Lets go and get another one!!!
Great product at a great price very well made easy install great fit just as good as oem
Worked perfectly to fix the transmission mount issues- no more slop
This product works ! Night and day difference. Easy install
This product was great . My 2001 Forester would shake horrendously, but after installing the transmission shifts much nicer and the shake has diminished. Would recommend.
This thing is awesome! completely stiffens up the driveline to where it should have been from the factory! I am surprised but also not by Subaru’s choice to leave such a big void in the factory transmission mount. The mount is designed to fail prematurely due to there being such a large void between the rubber points, this rectifies that issue PERFECTLY.
After having the insert installed there was a lot less vibration on acceleration! Well worth the cost!
No issues with installation or performance.
Rectified alot of drive line vibration.
I imagine if i had healthy control arm bushings i would have even less or nondriveline vibrations caused by after market cv axles
Thanks for the review!
The insert work very good I still have a little wobble but much better I have put new cv shafts on the front had a real bad wobble now its much better still would like to get rid of the rest of the wobble I am asking if there is anything else that would help with the wobble
thanks Robert
Bushing came well packaged and with some lubricant for insertion process. Using a small benchvise to fit the insert to the mount I found some outer lips of the insert needed to be trimmed off with a sharp Stanley knife.
This was to allow some relief during the start of the press fit proceedings in the vice. The supplied rubber lubricant helped this fitting process as described in video.
The transmission now is held tight with some flex in the mounts.
No more rattling on ignition start up and more confidence in off road driving.
Awesome hardware for the forester.. skid plate fitment spot on. Looks good in the woods . Would buy again.
So I order the bushing insert for my 2004 Subaru Forester MT and this bushing does not fit well. Even with a new OEM transmission mount, the bushing does not seem to fit as it should. Some of the slop is gone so it does work I just wish you would make one that would fit my transmission mount.
