Select - O - Speed AKA SOS It's a 10 speed 'automatic' tranny.. up and down shift on the go.. and 2 reverse speeds. Dash Cable pull operated independent pto. When the SOS trannies work.. they are like sliced bread... great speed control ( better'n an 8 speed )... when they have problems.. it can be anything from a 25 cent part to a few thousand dollars. If ya got a mechanic that will work on them you are doing good. If the one you look at is operasting in all ranges. and shows no problems.. maintain it well ( it is picky on oil ) and it will probably stay healthy for a long time. If it already has a few 'catches'... you mind find it cheaper to burn money in your fireplace to heat your house for the winter... SOS got it's bad name fromt he first ones that came out.. field failures.. I hear there were many field repalcements... As the production went on.. so did quality and loengevity. Since the first ones hit in 59 with the 100 series.. you at least aren't on the 'front line'. Good luck.. and test drive it cold and hot and in all ranges before you sign the check.. no need to spend money at the same rate as.. say.. howitzer shells that may have been used during the opening hours of normandy if ya don't have to... ( ps.. there are a small handfull of real SOS owner/guru's here than can help with common small problems.. and at least tell you how to troubleshoot or offer advice on how to fix or locate parts ont he 'money-pit' problems.. ) soundguy
