What makes a transmission mount go bad?
Transmission mounts normally fail after 60,000-100,000 miles or more, due to oxidation and vibration. Oxidation causes the rubber or urethane in the mount to fail. Vibration causes the steel bracket to fail. Improperly lifting the engine and transmission assembly during removal may result in broken transmission mounts.
