What type of oil/fluid is used in the transfer case of a 1988 F250 4X4?
I got a hold of a fluids chart . It does use ATF .

Originally the Borg-Warner or New Process transfer case in your F250 would have used Motorcraft® Mercon®; Ford Motor Company and the aftermarket now use a Transfer Case Fluid that splits the viscosity difference between Type F and Type A, but provides anti-oxidation properties consistent with Motorcraft® Mercon® LV.

80 or 90 weight gear oil.
