Where is the transmission mount?

I have some vibration and vibration noise at idle in park, more profound in drive, and next to nothing in reverse. It is a GLS with a V6 and the garage my daughter took it to said it has bad transmission mount, and also needed a right tie rod end and right lower ball joint. From my understanding there are three motor mounts one on top at the right fender well, one at the firewall, and one at the radiator. I understand that there is an additional mount at the transmission assuming somewhere in the left fender well area but cannot find it or find access.
