I replaced the driver and passenger mounts (both Uro parts). I did not replace the trans mount. 6 months later, The Passenger Mount was flat and torn a little bit (Pictures). I just today replaced the Passenger Mount with a Mercedes OE Mount($130). Also I replaced the Transmission Mount(Uro, $60). The driver mount is Uro and seems ok. After installing the Passenger mount(OE), I lowered the engine. The new passenger mount(OE) is sagging down just the same as the driver mount(Uro). I would think it would hold better. Here is a video showing the engine being lowered onto the mount along with some music: Youtube-Motor Mount
