Identify Trans by shifter?

[o1marc]

Can anyone tell me what tranny might be in this bus by looking at the shifter. It's got a DT466, 2000 Int. Amtran

the AT545 and MT643 used the same shift pattern and shifter.. 'R-N-D-3-2-1'
an MD3060 will have a pushbutton shifter with a digital display on it.

an Allison 2000 series will have 'R-N-D-4-2-1' or 'R-N-(D)-D-2-1' {seen these both way}
