Yes, I believe so. Hacking the bell off isn't a problem, but I don't know about the bolt holes. If there are already holes in the tranny to line everything up, no problem. If I have to machine the holes, I'm SOL because I don't have a machining center here at the house.
This is why I like it when companies make their installation instructions available. I guess I'll start looking at pictures of 4R70W trannys closer...
Also, anyone have experience with the aftermarket stand-alone controllers for these?
