Example: MO-13Z12A-A13
First Digit M = ZF Meritor
Second O = Overdrive, no letter = direct drive
Third and fourth digits 13 = 1300lb*ft input torque rating
Fifth Digit F, G = 9 and 10-speeds, Z = Freedom line
Sixth and Seventh Digits 12 = 12 Speed (forward gears)
Eighth digit = Ratio
Ninth digit A = Automated, S = Shift by wire, M = Manual.
Tenth and eleventh digits 13 = Highest torque in top two gears 13 = 1300lb*ft
Meritor Example: MO16F10
First Digit M = Meritor
Second O = Overdrive, no letter = direct drive
