Whether you need components for Ford or GM, G FORCE offers them in the size you need to fit different makes and years of vehicles.

Symptoms of Transmission Mount Failure

A broken or badly worn transmission mount can create excessive driveline noise and vibration. It may even affect the operation of either your clutch, gear shifting linkage, or both. Depending on the severity of the wear, it can allow the transmission to move too much and even hit the floor of the car on hard launches & takeoffs. Excessive wear can also cause transmission cases to crack and break from too much twist and movement of the driveline while mounted firmly to the rear of the engine.

Be sure to replace your old worn out trans-mount with a G Force Transmission Mount replacement part. They are the best you can install and will last for a very long time, giving you years of worry-free performance with your transmission. Our transmission mounts are available for both GM & Ford applications.

Transmission Mount Replacements made of super-strong polyurethane

G Force Performance Products sells transmission mounts made from a super-strong polyurethane material, which results in a significant performance upgrade over the OEM plain rubber units. Because it is so much stronger and more durable than rubber, it will not dry out, shrink, crack-apart, melt, or crumble away from high heat cycles like rubber can do. It is also not affected by transmission oil, grease, gasoline, engine oil, brake fluid, or antifreeze spilling down onto the mount from leaks or drips above from engine compartment.

  • The mount adjusts from 1″ in. – 2.5″ offset, which helps you reach your transmission crossmember mounting location, and it slides in either direction–forward or backward as needed for your car. To adjust the mounting location, simply loosen the horizontal Sliding-bolt, and slide the bottom mount-plate towards your transmission crossmember. Align the two studs downward, into the crossmember, and secure with the provided nylon lock-nuts and washers. Finally, tighten and secure the horizontal Sliding-Bolt using a torque-wrench to 20 ft./lbs. of torque.
  • The Adjustable Transmission Mount is 1.75″ tall.
  • Adjustable Transmission Mounts are made from sturdy 3/16″ in. thick steel, powder-coated for rust and corrosion resistance, and include high-strength Grade #8 mounting hardware. They feature polyurethane bushings to absorb road vibrations and harmonics. The Adjustable Transmission Mount fits most GM applications, including Chevrolet, GMC, Buick, Oldsmobile, Cadillac, Pontiac, and Jeep vehicles.
