the a3xx series of trans's are modular. you are able to swap bells, tails, etc from all different ones, 2wd, 4wd, lexus, cars, trucks, old..... Ive always wanted to see if you could put a a340f tail on the 343, or use the 343 bell and put a 340f on the 1fz. Then you can adapt to mini's. Or the ax15 (found in the cherokee) is also a aisin 300 series and has a tail that can bolt up to a d300 with no adapter....![]()
Do you have access to a 340f?
I think I have read the output shaft on the 343 is bigger diameter, but that doesn't mean the output shaft can't be swapped.
