AC D14 Transmission - Illustrated Parts Manual ?

My research and discussions thus far lead me down the road that AC did not document at least through Dealer Parts manuals some of the various "as equipped" utility/light industrial designs since AC at that time was just entering the backhoe/forklift - light industrial business. My thinking is  that there were machines built and sold for which the AC Design and Engineering Department did not elect to document.  Perhaps production numbers were low and Engineering knew that the Design would be changed at a later date to include a shuttle shift.   Another thought the crossed my  mind is that the Henry Corporation was building and selling the same backhoe and that the backhoe that I have was a dealer add on to the D14, that would be entirely possible since the paint under the AC orange is International Red.  But why would all the D14 Illustrated parts manuals only show the power director transmission parts and not the shuttle or 4 speed? 

Anyone have a D14 Illustrated Parts manual that shows a transmission schematic with just a 4 speed?   I hope I have included this in the correct section of the forum, as the D14 goes with the farm equipment side, although the hoe would go on the Industrial/CMD side of things.  

Am open to insights and suggestions on why there is no parts catalogs that deal with the D14 Utility tractor 4 speed transmission?

The transmission is the same regardless if it had a power director, shuttle shift or neither one.  Shuttle shifts were not an option for ag tractors at that time.  Power directors WERE an option - not standard equipment.

I replaced the transmission in my 59 D14 with a transmission from an industrial model.  I just had to add the bearings to accommodate the PTO shaft (which did not come on the industrial model I got it from).  The power director (or shuttle) goes on the input shaft OUTSIDE of the transmission.
