I've read that some 4.0 V6 vehicles use an A750F transmission and some 4.7 V8 vehicles use the A750F transmission. I've also read that the 4.7 V8 can be swapped in the place of the 4.5 1FZ-FE. So would that mean that you could bolt a RA61F to a 4.0, 4.7, and 4.5? The only reason I ask is because I had an FZJ80 and I disliked the auto tranny. If I could do a manual swap without having to import a $5000 transmission to the US, I would love to get another 80 series. And I have a FJ cruiser with RA61F 6speed. Although I'd hate for anything to happen to it, I plan on reusing parts from it if the time comes.
