The 8HP transmission comes only in longitudinal form for rear- or all-wheel-drive vehicles, and we prefer it immensely to ZF's transverse alternative, a nine-speed. In 2017, some 3.5 million 8HP.

I just finished swapping a 8 speed auto from a dodge ram into my 67 chevelle.
I'm posting this only to offer anyone interested in doing this any help / advice based on what I did to make it work.
it's really not too bad, I decided to rip the existing controller out of the tranny and used an external one.
other than that I used an ati adapter plate and 153 tooth gm flex plate to mate it up.
I am currently manually shifting using two buttons, shift up and shift down. I'll be adding auto mode someday however manual mode is really what I was after,
I actually only lock up the converter after 8th so it feels like a 9 speed.
it's basically the same as the hellcat tranny, I shift in under 200 ms and it barks the tires in every gear.
there's probably better trannys to use but I've tried 2sp, 3sp,4sp od, and a t56. This 8 spd kills them all
Again, I'm only posting to help others interested in doing this, it took me a lot of searching to find the info so I'd be happy to help anyone save some time do this.
