Can bad motor mount damage transmission?
Transmission damage via bad motor mounts isn’t the most common type of failure, mostly because the U-joints and CV joints will usually — by design — fail before anything in the transmission will. Engine twisting may alternately pull the retainers out of their grooves and shove them back in.
Where are the engine and transmission mounts located?
The engine and transmission mounts hold and support the powertrain while isolating the vibrations produced by the powertrain from the chassis. On rear-wheel drive (RWD) cars and trucks, there is usually a pair of motor mounts on each side of the engine to support the engine, and a single mount under the back…
Where are the motor mounts on a rear wheel drive car?
On rear-wheel drive (RWD) cars and trucks, there is usually a pair of motor mounts on each side of the engine to support the engine, and a single mount under the back of the transmission. The rear mount may be part of a bolt-in cross member support.
