Only rather late model Allisons have overdrive top gears. As in--the MD3060
and HD 4060 'world trannys' which are six speeds, are OD in their two
highest ratios, and the (even later model) 1000/2000/2400 models are five
speeds with a single OD ratio.

All of the above are electronic control. You are NOT very likely to find
ANY  of them on the cheap.
