Anyone know if Mitsi 2.8 and 3.5GDI auto boxes are the same?

As above really. That's all I need to know. Original plan was to use the 2.8 Pajero box for my conversion but I've got first refusal on a tiptronic auto box from a 3.5GDI for a really good price. Tried to call Mitsi but they said they can't help me unless I have VIN or registration numbers. Really just hoping some of you Mitsubishi converted guys will know.

I do know they are both AISIN boxes. So it's a very high chance but confirmation would be awesome.
