My '96 Bounder has Milwaukee Cylinder leveling system - I assume yours does also. The manual states 2 possible causes for the light not going out: 1) Low fluid level, or 2) Fluid level switch malfunction. Also states to use Dexron II ATF, but any type A ATF will work satisfactorily. There are other options for cold weather operation (Mobil DTE 11M, Texaco Rando HDZ-15HVI, Kendall Glacial Blu, or any Mil. Spec. H5606. Fluid level should be at least 1/8" from bottom of dipstick (located near top of fluid pump tank; appears to have a hex-head knob). Float switch is also near the top about 90 degrees from the dipstick. Two wires connect it; check for continuity and/or corrosion if fluid level is o.k.
