Overheating Tranny
I have a 93 Ford F250 Heavy duty diesel,, with a 7.3 IDI non turbo engine and 4 wheel drive.. I bought the truck in Oct and never had a problem till it got warm in may, the tranny in my truck has a blow by valve for when the tranny overheats, it will release it, by letting fluid out.. so i changes the filter and fluids, but the *******s gave me regular synthetic atf,, it still did it,, so yesterday the radiator blew, so i replaced it and put a new external tranny cooler on it,, and it was doing good untill this hott *** weather today,,, so my thought is,,, is that synthetic messing with my truck, since what was originally was in there was the regular dinosaur oil... or what should i do period???

Synthetic isn't going to harm your trans. Lack of cooling is probably your problem, and if you don't have a cooler in the radiator (I couldn't tell from your post) then it's probably going to overheat.

blowby valve
The only reason fluid would blow off is because it has heated to the point of over expansion and has puked out of the breather.
Find the cause before serious damage happens.
The transmission or convertor are slipping or the cooler is insufficient.
