Anyone know if the 4T60E transmission from a 1995 Buick Regal 3800 will fit a 1995 Park Avenue 3800 N/A?
I'm asking in regard to fitment compatibility with the frame, and in regard to wiring.

The transmission should be the same, however, the mounts might be a little different. But you should be able to move the mounts from your old trans on to the new one.
Biggest thing is the bolt locations on the back of the trans. i'm unsure on the 60'* if all had webbing and three bolt bosses in back. On the 65'* it is about a 75% chance the bolt bosses are there. The Park Ave will need the bolts for the rear trans mount.
