  • High-Low Aux Trans
  • Are the aux trans specific to 9N, 2N, or 8N, or are they interchangeable? There is a 9N or 2N in a salvage yard with a high-Low aux that I would like for my 8N, if it is compatible. My brother is there and texted a pic of the tractor, or what is left of it. I an not sure if it is a 9N or 2N, but it is clearly not a 8N. He said the aux shifter popped into 3 distinct positions when he moved the lever. Any advise is greatly appreciated.

  • Re: High-Low Aux Trans
  • Not the proper name but yes people call them over/under trans and some people call them a High/low trans and some people don't know that you can pull the combo shifter out for the standard range

  • Re: High-Low Aux Trans
  • I view your photos and itís a step up or a step down Sherman. The step up value is about a couple to few hundred The step down value is $500/$700. Location has a lot to do with price. Step up has grey case. Step down has red case

  • Rarely found and almost never mentioned the other Sherman. It was the reversing version. Great if you had a loader on your N. Neighbors bought a new loader 8N with one, can't tell of the fun we younger folks had with it. Just imagine going backwards in 4th gear reverse!

  • Re: High-Low Aux Trans
  • The correct term is the Sherman Step Up/Step Down or the Combo Transmission. The first Ford 9N aux tranny offered by Sherman was the Step Up as farmers wanted a faster road speed to get to and from their fields. Time is money. farmers would head out in the morning to farm/work as quickly as possible and then return for dinner (we call it lunch now) in mid-afternoon and then get back out to farm more before dark and head home for supper. We have a lot of info here on the Shermans in our MANUALS and HOW-TO's forums -see LINK for one. Also, the CLYMER/I&T FO-4 Manual has a section on Sherman transmissions and the 53-59 MPC also does too. Frequent member Kirk-NJ knows a lot about the Shermans, has a few, and a has rebuilt a few. Archive search ALL keywords with his name and Shermans and you'll get over 125,000 hits.

  • I don't know what you are having to pay for the trans your brother is looking at but to give you and idea, I have a Sherman combo that I have sold (as soon as the stay home lifts). $800.

  • Re: High-Low Aux Trans
  • It will fit. Be sure to get the right template for the shift lever hole.
    "He said the aux shifter popped into 3 distinct positions". Yes, a 2 speed will do that. Standard range, neutral, 2nd range. Notice that I did not say high or low. It could be either.
    A Sherman combination aux tranny will have 4 positions. In the neutral position, the handle will slide in toward the trans. case or out depending where it starts. This allows 3 speed ranges. Out and back toward the driver is "standard" range. It is the same as if the aux did not exist.
    Forward to neutral, in toward the case and forward again is low range. Forward to neutral, in toward the case and back to you is high range.
    The shift levers for a hi-lo and a combo tranny are different. The hi-lo has a straight handle coming off the shaft and back toward you with a ball top. The combo tranny has a "dog-leg" handle that corves forward and then comes back toward you.

  • Re: High-Low Aux Trans
  • There is a second 9/2N there also with an aux that has a shifting arm that has a twist at the base and a long straight handle with a plastic knob.

    What I need is more power to the wheels at low driving speeds, like a granny gear and another gear half way between first and second. I am running an arps half track and the deep snow is almost too much for first gear.

    For my situation would a high-low or a combo be best?

  • Re: High-Low Aux Trans
  • What Carl said. You want the Combination trans that you described below. Step down first and step down 2nd are both lower speed than first gear. Also understand, changing the input to the standard transmission also changes the RPM of the PTO if you are going to use the PTO.

  • Re: High-Low Aux Trans
  • As far as I understand, their is no such thing as a "high-low". Their is a high-standard and a low-standard and a high-standard-low (also known as the combination).. For you the High- standard would do no good. You want the low-standard or the combination. Combination will give you 12 forward and 3 reverse. The other two will give you 8 forward and 2 reverse.. Now that is just my humble opinion..

  • Re: High-Low Aux Trans
  • The "high-low" term has bounced around for years. I think part of it is a result of people not knowing which shift range is the standard range, just that one is higher than the other. I'm with you. I would like to verify because I do not have a Sherman step down, only step ups and combos. I do have 2 F&T step ups and 2 Hupp combos.

  • Re: High-Low Aux Trans
  • I only have a Combo. But then again, I only have 1 8n.. I have a NH TC29 that I do most of my stuff with. I pretty much only use the 8n to load logs on my sawmill, it will lift most anything, including the back wheels...LOL Yes I am careful, I know the front end is weak..

  • Re: High-Low Aux Trans
  • LOL. You just reminded me of what I did with the 8N (Nellybelle) that I have been driving since I was 10.
    In 1985 we built a new house and I moved about 1,400 yards around with Nelly and the Wagner loader that she has worn< and been off< for close to 60 years. Her rear tires were loaded with chlorid.
    This was very wet heavy clay soils. There were times with a full bucket I hit a small dip and both rear tires raised a foot or more above the ground. To this day I do not know how I did not break the front axle.
    I have heard horror stories of the axle breaking and taking out the whole front of the tractor, crank pulley, hydraulic pump shaft, water pump, radiator and anything else that things breaking can destroy.
    Nellybelle only carries me or one of the grandkids today, only as a driver.

  • Re: High-Low Aux Trans
  • HaHaHa... I went to put a 21 foot log on the mill to cut some rafters, I lifted it a couple inches off the ground but couldn't go anywhere.. That's with a 7 foot back blade with a small log strapped to it for counterweight..Went and got my sons 65hp Heston and couldn't begin to lift it.. We had to use both tractors and I gave him the smaller end...LOL I took the bucket off and made a gambrel so the log was closer to the tractor, mounts right where the bucket would..

  • The lever is a short dog leg with a small ball cast on the end.

  • Dog leg handle was also used with the creeper box. Creeper gearbox was painted a copper color.
