How to Install Transmission Mounts
Your car's transmission mount is the one responsible for isolating the transmission from the passenger compartment. It may be just a small component but it can greatly affect a car's performance when it gets worn and its rubbers get old and brittle. Faulty transmission mounts can result to shifting problems because of the transmission's misalignment with the chassis. If you think your transmission mount needs a replacement, here's a helpful guide on how to install it yourself:

Preparing for the task
Before installing new a new transmission mount on your car, make sure that everything is all set and secure. First, raise your car's front end from the ground using a jack and use four jack stands to support it. For the height reference, make sure that you have raised your car within 1/2 inch of the transmissions' height or the oil pan from the floor. After that, you can now go under your car and look for the transmission mount.
Removing the old transmission mount
Slightly raise the transmission by sliding the jack underneath then soak the bolts in penetrating oil. To access the transmission bolts, remove both pipes at the transmission unions so that the exhaust pipes are spread apart. Next, remove both bolts that attach the spring support bottom to the transmission by using a ratchet set. After that, you can now pull the old transmission mount out from between the metal beam and the transmission.
Installing the new transmission mount
Once you have removed the old and worn mount, you can now insert the new transmission mount in the same spot where you removed the old one, between the metal beam and the transmission. Tighten all the bolts using the ratchet set then raise your car with the jack to remove the jack stands and finally, lower it back to the ground.
Tips and warnings
- Before removing the four-perimeter screws, make sure that the transmission mount is supported by a floor jack.
- Don't forget to check if the transmission crossmember has cracks or damages at the slotted hole areas. If you see signs of damage, replace or repair the crossmember first before installing the new mount.
