Am I the only one who's noticed that the NPR auto transmission is an Aisin A450? I've seen pictures of them on eBay. The A440 and A450 both have a detachable bellhousing. Am I the only one who's wondered if the front side of the A440 and A450 might happen to have the same bolt pattern? If so, you *might* be able to use an NPR auto bellhousing on the front of an A440. Of course, you'd still have to deal with flex plate and torque converter issues, but it's a possibility...you'd probably have to have an A450 and an A440 next to each other to figure it out.

That would be great! I have both a A440 and an Isuzu automatic. Unfortunately, the Isuzu is under a pile of snow, however, I'll try to take a look. to you if you are correct!
