yes, transmission as the jacking point, BUT I didn't really have to jack it up, I just put it there supporting it. After I took the mount off I played with the jack and the motor didn't move much.
Also, for the getting the throughbolt off with a breaker bar, the best way that I found was driving up on ramps, unscrewing that plate right underneath/next to the mount, and using the breaker bar from below. I didn't have much room to use it from above.
then once I loosened it I got off the ramps and set the jack on the engine and undid all screws.
