OK, had both engine mounts and the transmission mount replaced yesterday. The car accelerates more smoothly now.....

There is, however, a transmission fluid leak. I spoke with the technician who said he believes there is a rear main seal leak (where the engine connects to the transmission). I notice transmission fluid on the floor in the garage although I am not sure it is coming from the back of the engine.

I am thinking of putting the car up on jack stands, spraying the under carriage with Sam's Club degreaser then use my pressure washer (I have a 90 degree wand) to clean the grease off the under carriage.

Any other ideas to help find the source of the transmission fluid leak?
