I dont know what it is called, it is on the back part of the tranny...has six bolts that attaches it to the rest of the tranny and the crossmember attaches to it. it is leaking where these two connect and i need to replace the seal. not sure how to get it undone and out...do i need to remove the crossmember? do i need to use a jack to hold up the tranny and if i do where do i put the jack? i posted this in the 5.0 tech forum, but i have a sn95, my bad. thanks.
