Considering the kind of vehicle you have and the brand you choose to get the component from, you can find motor and transmission mounts that are priced as low as $50 and as high as $550. Transmission Mount Cost of Replacement The part is usually $50 to $200 itself, and labor is about the same. When the stable foundation of an engine or transmission becomes defective, other car parts begin to suffer as well. Therefore, when transmission mounts collapse or wear out, they adversely affect engine stability, resulting in a flexing vehicle frame that eventually makes the car difficult to drive. Top 5 Bad Transmission Mount Symptoms #1 – Clunking, Bashing, and Banging Sounds. If it sounds like your engine is trying to break out, that's an example similar to a loose transmission mount noise. #2 – Thumping. #3 – Excessive Vibrations. #4 – Chassis Flex. #5 – Difficulty Cornering. The labor guide gives between. 8 and 1 hour labor to replace each of three motor mount.
If your vehicle is 20+ years old and has over 275k miles on it, then the cost of repair or replacement is most likely higher than the value of the vehicle. In this case, it's typically not worth getting the car fixed unless it holds significant sentimental value.
The transmission mount is one of many drivetrain mounts found on most cars and trucks. Most vehicles have two or three engine mounts and at least one, and sometimes two or more, transmission mounts. Along with bell housing bolts, the transmission mount keeps the transmission safe and secure underneath the hood.
When a transmission mount breaks, a large part of the transmission weight becomes unstable, and in severe cases, the strain of the unsupported transmission weight can cause parts of the transmission housing to crack, break, or become warped.
However, bad motor mounts will eventually create a host of problems with your engine, chassis, transmission and drivetrain, owing to excess engine/transmission movement and -- over a long enough period of time -- excessive vibration.
Over time, it's fairly common for the engine mounts to weaken. In some severe cases, a mount can even snap. If any of the motor mounts aren't securely keeping the engine in place, it will cause problems and it can make the vehicle very dangerous to drive.

Transmission Repairs Often with a transmission repair, you are only fixing one specific part of the transmission. This repair can take place without having to rebuild the entire transmission. This option typically costs less than a rebuild or a replacement.
This could be caused by a few things from my experience, (1) low transmission fluid will cause shifting to occur at higher rpm's causing it to jerk (2) a broken transmission mount will cause rough shifting for the simple reason that it is off its mount. (3) a stuck governor will also cause rough shifting.
If the transmission mount breaks completely, the transmission may shift during acceleration, causing a knocking or clunking sound. If the transmission shifts and twists severely enough, it may damage other components, which cand result in additional noise and possibly damage.
Grinding or odd sounds: Automatic and manual transmission both make unique sounds when they start to go bad. On an automatic transmission, you may hear humming, whining or a buzzing sound. You'll also feel as if every gear is wobbling into place.
How to Replace Transmission Mounts Park the vehicle on a flat, hard surface for lifting. Center the floor jack's armature under the transmission pan of the transmission. Raise the floor jack until the bolts of the rubber, shock-absorbing mounts can be removed with the mounts.
