It actually will freewheel in 5 forward speeds. It's just that 1&2 are so slow they didn't think it would be a problem and didn't mark the shifter in those positions.
An easier way to tell is to look at the casting # on the left side of the transmission. A 312259 above and behind the inching pedal is the original less desirable transmission. Anything else there is better.

I am considering buying a 871 - year unknown as I couldn't find the serial number over the starter housing. I did see a number on the side of the SOS, but didn't write it down. Have reviewed some of the threads and am concerned (to some degree) about the SOS as I have a Ford Industrial 4400/loader that REALLY sluggish shifting into reverse.

I have a 1958 851 with a 5 speed (an bad engine). I am considering the option of replacing the SOS with the 5 speed if needed. I see someone did this to a 801 in another post - but current owner didn't do.

Can anyone tell me if is possible, and if it is, how difficult (and costly???).

New to forum, so open to critique .

It would be better to start this in a new post (that's my critique :wink: )

It is very possible to convert from one trans to another and many would advise installing the 5 speed in place of the SOS. I'm not one of them! I'd sell the blamed 5 speed to one of its advocates and fix the SOS - if indeed there is something wrong with it.

Thank you "Showcrop" and "Larry". I will check that number and get back to you (because I don't know what it means to "freewheel" :-)
