" From: Joe <jgray_55@xxxxxxxxx> " " So far the transmission fluid shows NO coolant in it!! " Whew!! So now i have a slightly dumb question? What " fluid does the Borg Warner auto in my 67 Ambassador " require? I've never had to add to it.Does it take " Type F or Mercon/Dextron? I know years ago you used to " be able to substitue F for dextron..did not hurt a " thing. Just could not use dextron in a F trans.I'm " going to install the after market cooler.Thanks again,Joe type f was only for fords, including the fmx, but nearly everyone else uses dexron/mercon - including ford now. iirc gm, mopar, and warner always used dexron/mercon. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
