Need some help identifying this tranny, I didn't come up with much on a search. Numbers read 78 BB 48974 411 on top. My 69 442 is supposed to have a th400 with 2300 converter but I see this tag on the side of the trans. She runs good but curious to what it really is.
No, I can see the bolt on governor cover, the governor cover for the THM350 is on the other side and is press in with a clip.
