New to Mopars---BUT always a cool different car fan.

Two levers up and 1 down? ain't it??? OD.... Or am I backwards!!!
The information that I had was that if the transmission Body and the bell housing are aluminum, then is is 100% that is is a 4speed OD unit... Based on this info, I have the tabs with 1/2 up, 3/4 down and reverse down...

My next step would be to possible turn 3/4 back upright and maybe assume that the tranny is not an actual OD unit..(prior owner stated that it was an OD also.) I have numbers off tranny, but cant find anywhere to help to decode this yet....
anyone able to help with this info?

Numbers are - C178617 PP63_ 5324
C13305 - (on tail shaft)
Thanks,
