Is there much of a difference between AA and BB transmissions? How do I tell them apart? What parts are interchangable? I have three to choose from.
One is still in the truck. One is in my parts truck with a busted case. And the last one, I got real cheap. I think this one might be the BB. It came with a PTO assembly that I plan to use in my project.

Re: AA vs BB transmissions?
The BB bell housing is different and they don't have the pedal mounting shaft on them. All the BB gears will go into the AA case.
