The 4R70W is a Ford transmission, and generally considered an evolution to the AODE, a transmission that it is often interchanged with.So we’ve redesigned it so we have a complete strength in the system inside, then everything’s tied together. These planetaries blow up, the pins come out and wipe it out, which is kind of unique, but again, because the planetary was kind of wimpy the way they built it, you needed a lot of strength.
