How to ID Sherman Transmission

I posted pics before of the 1943 2N up the road. It apparently has the factory installed Sherman "something" transmission. I was told below that you cannot tell which Sherman transmission it is without the tractor running.
I hope, in the coming days, to get back up there and see if it will crank. Assuming it does, how do I tell with the tractor running? As stated below, the shifter "seems" to have 3 positions:Forward, Middle, and Back.
I guess I need to answer this question....
I put the tractor in gear and....??

All guidance is appreciated...

"Forward, Middle, and Back. "

Most likely a step up.

Forward = regular speed

Middle = neutral

Back = step up
 
Thanks Guys!

Assuming the "Step-Up" scenario, I should be able to:
->put in 1st gear...with Sherman shifter forward..Slowest speed.
-> Shift to 2nd gear, with Sherman shifter still forward - next slowest speed.
-> Shift back to 1st, and pull Sherman lever back - next higher speed.
-> Shift to 2nd, with Sherman shifter still back - Next higher speed
-> Shift to 3rd, with Sherman Shifter forward...Road Gear 1
-> Shift to 3rd with Sherman shifter back - Fastest Road Gear.

This sound correct?

I will post what I find....Planning on going Saturday afternoon late.

Thanks again!

I looked at the pics you posted in your earlier thread, its definitely NOT a combo- they have the handle location in a different spot. its either a step up of step down.

That is the same location as my step up. If I was a betting man, I would bet its a step up, as those seem to be the most common trans.

you are correct in that forward its normal range, middle is neutral, and rear is O/D.

You dont even need to move the tractor to tell, if you can get it to run, engage the pto and try the 3 positions. I can clearly tell when I have my trans in OD the PTO is spinning much faster.
 
FYI, Shermans being factory installed is a common misconception, at least in the early years. Ford did not start installing them at the factory until at least 1953, maybe a little later, and those would have been the combination (high/direct/low) and reversing in the 4-speed transmissions only. Until then, they were dealer, repair shop, or owner installed.
 
Do not shift while moving! These transmissions are not synchromesh. Pick the trans gear according to what you are going to do and leave it there until you come to a stop.
 
Step-up and step-down have the same lever, round rod with round ball. combos and creepers have the dogleg style handle.

Ya know, I was totally forgetting a regular under drive and only thinking about the under driving creepers :)

both of those are as rare as hens teeth here, combo and of are the common ones here, used to see more of, but now, not so much. Occasionally see a hupp or Everett or one of the other shermans like reverser or lpto, but them rare here too
