Pardon my ignorance, but I am new to the AA's. My '29 AA dually bus has the 4 speed transmission with the finger switch for 1st and reverse. It also has either a hi/lo auxiliary transmission or a 2 speed axle :?: . It is operated by an arm that lifts up just behind the main transmission tower. I don't know how to operate it. in the down position, the main operates normally. But when I lift it, everything seems to go to neutral. So the question is: how do I operate this thing? :?: :?:

Ford factory 1929 AA's did not come with dual rear wheels (nor could the 1929 axle accept dual wheels). Pictures of your truck would help id it. The 4-speed transmission did not come from Ford with the extra transmission referenced. Pictures would help id it. And, it is unlikely that the rear axle is a "2 speed".

As it turns out, it is a Warford. It is in line on the drive shaft behind my 4-speed transmission. The shift lever has 3 positions- bottom, midway, and up. How do I use it?

The Warford transmissions that I know of are three speeds (under, direct, and over). See attached

Thanks, Neil. The diagram helps a whole lot. Now I need to play with it and develop my finesse on what works best. Thanks again

It is a non-syncromesh crash box.

My suggestion is to put the Warford in high and not try to change gears when moving. The 4-speed can be used for shifting while driving.
