Useful datasheets for AT545 MT643 and MT653

I was doing some research and came across some useful spec sheets for teh AT 545 MT 643 and MT 653 transmissions. I figured other people might find them useful so I'm posting them here. It lists the gear ratios, rated torque/hp, weight, dimensions, shift sequence, SAE #, etc. and also includes schematics.

Looks like there is:


Allison 1000

Allison 2000

Allison 3000






Also found this Operator's Manual for the Allison 1000/2000 series "PTS" (pupil transport system)

Hey DLZ. I just bought a bus with the 545 and then read all the potential problems with this tranny. Information is power. I’ll study up on it and feel better. Thanks for posting these.
