For the record GM and Ford just finished co-developing a 6spd auto transmission. So yes, from time to time, they do work together. But Ford is much more likely to pawn car parts off their other units. The Fusion chassis (Mazda 6) and I4 motor (Mazda), the Five Hundred chassis (Volvo S80), the Euro Focus ST I5 motor (Volvo), the Escape chassis (Mazda 626) and hybrid technology (Toyota), the 2.3L Duratec (Mazda), and so on... Ford is just the epitome of platform sharing these days. Almost nothing is Ford anymore, it seems.
