If Lonnie is talking about the original HydraMatic transmission on a 1/2 ton Chevy truck (with enclosed driveshaft), what is meant by a dual-range model?

I recall that the shift indicator has settings of something like "1-2", "1-3", "1-4", and "R".

Thanks,
Tim

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
