Transmission Mounts

Transmission Mounts: hold the gearbox still so your drivetrain works as one

A transmission mount cradles the rear of the gearbox and ties it to the crossmember or chassis. Its job is to locate the transmission, carry its weight, and soak up the twist and vibration coming off the engine and driveline. When a stock rubber transmission mount gets soft, cracked or oil-soaked, the whole drivetrain shifts under load - you feel it as clunky shifts, driveline slop and vibration. Fitting a fresh or stiffer mount pins the assembly down so power goes where you point it, which is why it's a common upgrade on hard-launched and tracked cars.

What ThreePiece stocks

There are 40 transmission mounts in stock right now, spanning 14 brands, with current prices from $28 to $11,185. That top figure is not a bare mount - it covers full driveline packages like the BD Diesel Towmaster transmission and converter package for 13-18 RAM 3500/4500/5500 and the BD Diesel TorqueMaster 68RFE with billet input shaft. The best-represented brand is Energy Suspension, followed by Torque Solution, Whiteline, Cusco, Prothane, BD Diesel and aFe, among others.

Coverage runs from 1968 to 2024. Of the parts listed, 25 carry fitment data spanning makes including Chevrolet, Jeep, Ram, Subaru, Mitsubishi, Dodge, Nissan, Ford, Honda, Toyota and Volkswagen. Popular platforms include the Chevrolet Corvette, Nissan 240SX, Ford Mustang, Mitsubishi Eclipse, Eagle Talon, Subaru WRX, Jeep CJ5 and Cherokee, Honda CRX and Volkswagen Golf.

How to choose

The main trade-off is compliance versus control. A billet or polyurethane mount holds the transmission tighter and sharpens shift feel, but passes more vibration and noise into the cabin - that's the cost of the stiffer material. The Torque Solution billet aluminum mount for the 2015+ VW Golf MQB with DSG is a solid-mount example of that approach. A rubber-style replacement keeps things quieter and closer to stock, which is what you want on a street or tow rig.

On the Corvette you can see the range in one platform: the aFe PFADT mount for the C5 (97-04) and the aFe PFADT set for the C6 (05-13) sit alongside billet options. Match the mount to how the car is actually driven, not just to the biggest number.

What else you need with it

A drivetrain that twists at the transmission usually moves at the engine and axle too. While you're under the car, look at Clutch Components and Flywheels if the clutch is due, and Differential Components for the other end of the driveline. Manual cars often pair a mount swap with Shift Components to tighten the whole shift path. Browse everything under the Drivetrain section to see what fits your build.

Fitment and ordering

Confirm the mount matches your exact year, make, model and transmission before you buy. If you're unsure, call fitment help at 813-535-5801 or reach us through contact us. Every order ships free, and Affirm and Katapult financing is available on the bigger packages.
