Thanks for posting the info, Greg!
The Jeep/Dodge AX15 5-speed, the Jeep NV3550 5-speed, the Toyota R150F & R151F, the 87-92 Toyota Supra Turbo R154 and the Isuzu AR5 5-speed all share the same case to bellhousing bolt pattern.
I'll go you one further -- all the trannies in question are of the same Aisin family... so substantial interchange is available in components... that'll come in handy when you want to adapt to a different bellhousing or flywheel, when you need a different input shaft length exposed, or when you want to swap a tailhousing to allow bolt-up of a different transfer case.
The real hot swap, IMHO, is the R151 with the stock tailhousing that allows bolting-on teh Toyota gear-driven transfer cases for which so many different gearing options are available... <img src="/forums/images/graemlins/kewl.gif" alt="" /> It is sorta non-traditional to think of the tranny as the adaptor, but the bolt pattern on the front of it is what allows attachment to so many bellhousings, and I remain flat-out amazed that the swap-happy Jeeper crowds haven't developed this path that much...
That's the root question I have, I guess.... why is this so poorly known? <img src="/forums/images/graemlins/confused.gif" alt="" /> Marlin started down this road, but I think he just got too busy to continue. Certainly a market opportunity exists!
Greg, you definitely have compiled a great amount of info on this -- great job! <img src="/forums/images/graemlins/grin.gif" alt="" />
