Bern, have you given any thought to flying around the country and fixing SOS transmissions? If you are like me, (I do handyman work now, mostly for family), it is like a curse. You should write a book! Take care.Hilltopper. (retired and I love it)

No thanks. Just like anything else, I'd get tired of them eventually. Beside, most of those SOS's are older than I am, so I'm by no means the expert. It's just that I have worked on a few in the past.

I'm more into the new powershifts. Electronically controlled versions. Sweet is the only word you can use to compare them to the SOS. However, I still maintain that the SOS was a decent trans for its time.

Bern; I agree that the early S-O-S trans were good for their time. They also pushed other companys to develope their own "power-shift" version. When you look at some of the firsts produced by Ford in just tractor history it is amazing! I hope to someday have a 981 or 4cylinder 4000 diesel to restore and modify, have to have working toys

Or, maybe other companies pushed Ford. It is common knowledge that the SOS was rushed into production before they had all the bugs worked out. Obviously, Deere was close on their tail with their powershift. They came out a year later with theirs.

The early SOS trans had their problems. The later ones worked out pretty well.

Like you I worked on the early SOS boxes that were brought into Englandon the '000 series. They were a good box if people used them right. Ford did demo's showing the instant change from 10th forward to reverse. When farmers tried this,or used the gears to slowing down on hills on road work etc. box could not stand it. The new electronic power shifts are so easy but CNH, along with the others, seem to be using very cheap electronic components such as switches and pots and really marking them up. We supply our local J-D dealer with pots. that cost us 4.50, the same pot. made by the same company to the same specification is normally 40.00 from J-D.
The transmission gear trains though are dead simple compared with SOS.But you do need some electronic experience as far as diagnosis is concerned.

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want unless you own a monster tractor. U ... [Read Article]
