[quote:398722a767] How much trouble can the SOS be?[/quote:398722a767]

The S-O-S transmission of the later 3 cylinder 4000 series, if properly maintained and adjusted, is a very strong and reliable transmission. That's what I have in my '73 4000 and it works great. If it has not been maintained properly then there could be problem. Also, if it is not adjusted properly you can have problems. The proper maintenance and adjustment, while a little more involved than just changing the fluid and filters, is not that difficult. If you do end up getting one, get the proper manuals and follow the procedures and it should provide you with good service. It is a 50 year old piece of equipment though and there could be something worn just like any other piece of equipment of that age.

[quote:398722a767]It is just a selector, not anything like hydrostatic?[/quote:398722a767]

The S-O-S transmission is not a hydrostatic transmission. It is a gear drive transmission in which the shifting of the gears is controlled by a hydraulic selector valve, which in turn engages and/or disengages various servos and clutches in a series of planetary gear systems, so that when the transmission is engaged in any particular "speed" or "Gear" the output of the engine is directly engaged with the pinion gear in the differential through the torque limiting clutch and the planetary gears. There is no hydraulic or viscous coupling between the engine and the drive axle like you have with a hydrostatic or even a torque converter.

[quote:398722a767]Do all of the 3 cyl 4000's have live power and power steering?[/quote:398722a767]

Power steering was not standard on the 3 cylinder 4000 series. It was an option.

I'm not sure what you mean by "Live Power". All Ford tractors starting with the 1953 NAA had live hydraulics. Live PTO was an option even through the later 3 cylinder thousand series with all of the manual transmissions except the 4 speeds, which did not have the live PTO available at all. The Select-O-Speed transmission tractors all had independent PTO, even the ones on the earlier 4 cylinder thousand series, and the '01 series as well.
