Overtake 6 Speed Transmission Mount Insert 2004-2021 STI/22+ WRX

The OVERTAKE Transmission Mount Insert Kit for the Subaru 2004-2021 STI and 2022+ WRX fills the open voids in your factory transmission mount with a molded 65A polyurethane insert, cutting the play the stock bushing allows without replacing the mount. The factory mount stays in the car, so you get most of the benefit of a stiffer mount for a fraction of what a full replacement costs.  That vague spot in the shifter and the bucking you feel as the clutch takes up both trace back to the same piece of rubber. Subaru builds the transmission mount soft on purpose. It soaks up drivetrain noise and vibration before any of it reaches the cabin floor, and on a quiet drive down the road that is exactly what you want. The tradeoff is drivetrain movement, which is where the slop in your shifter and the oscillation on clutch engagement come from. The Overtake transmission mount insert kit is built for the 2004-2021 Subaru STI and the 2022+ WRX to take that motion out while leaving the factory mount where it sits.

What You'll Feel: Filling the voids gives the gearbox somewhere to stop, and you notice it in the two places a manual driver spends the most attention:

• Tighter, more definite shifter throws
• Less slop through the drivetrain
• No bucking on clutch engagement
• Gearbox planted under load
• Smoother take-up off the line

Features:

• Molded 65A polyurethane insert
• Fills the voids in the factory mount, no mount replacement required
• 65A durometer chosen to balance NVH, performance, and ease of install
• Silicone lubricant packet included so the insert slides in without tearing
• 20 to 30 minute install with basic hand tools
• Molded in Overtake blue to match the rest of Overtake's drivetrain bushings

The Details: The usual fix for a sloppy transmission mount is to throw the mount away and bolt in a replacement with stiffer bushings. That does work, but it also runs into the hundreds of dollars before you have touched anything else on the car. Overtake approached the problem from the other direction. The play is not coming from the mount itself, it is coming from the open voids molded into the factory bushing, so the Overtake transmission mount insert is shaped to fill those voids and take the free motion out of the assembly. Overtake chose a 65A durometer material instead of something harder, because a solid or near-solid mount sends transmission whine straight into the floor, and 65A keeps enough deflection in the system to stop that while still pinning the gearbox down. It is also soft enough to work into place by hand, and a packet of silicone lubricant ships in the box so the polyurethane slides in without tearing on the edges of the mount. Plan on 20 to 30 minutes with hand tools on any of the manual cars this fits, and nothing about the install is permanent if you ever want the original feel back.
