Is that with a 7.3L and if so what year?

Mine is a V10, but it is also a 4R100. The V10 and 7.3L version of the 4R100 are the same. Even the torque converters are the same part number. The V10 does run locked all the time however, while the 7.3L will stay unlocked at certain RPMs and throttle position. I'm not sure if its actually a programing difference, or if its a side effect of where the two motors make their power.
