The specs of the fluid should be on the dipstick or in the manual. Although multi purpose fluids exist (ie. "safe for all transmission types") there are certain transmissions that are designed from the ground up to use a specific type (Dextron, Mercon, F, A, ATF-3,4, T-Type, etc) and using another type may affect shift points, temperature, quality of shifts, or worse. If you are so low that damage will occur or slippage and need a quick top off to get you home or to a garage, Dextron is widely compatible and will get you home. The only approved fluid for a Dodge Ram Van trans is Mopar ATF+4.
