Important: Before replacing any transmission mount due to suspected fluid loss, verify that the source of the fluid is the transmission
mount, not the engine, transmission or accessories.

following conditions:

The hard rubber surface is covered with heat check cracks.
*
The rubber is separated from the metal plate of the transmission mount.
*
The rubber is split through the center of the transmission mount.
