The round mount under the transmission on the drivers side closest to the radiator is shot at 51,000 miles.Is it the transmission mount or the motor mount?Is it referred to as both?Also is this the one people make the hockey puck mount for?I need one and advanced calls it a tranny mount and autozone a motor mount(if its the same one).Thanks for any info.

I believe that it is actually a transmission mount.

Yes, that is also the one that everyone makes the solid mount for, I have a solid mount on our '03 SSEi.

It is a transmission mount. If you look at the top bracket, you will see that it is attached to the transmission, not the motor.
