Selecto-speed shifting fails to work

Randall Johnson Select-o-speed
I have a 1965 ford 3000 that when put in gear the clutch and brakes dont work. I was told by the garage that it can not be fixed. The told me to remove that Tranny and put a standard shift one in. Can the old one be fixed?

Sean in PA The pedal that you think is a clutch pedal is called the inching pedal. it controls a hydraulic valve. When the pedal is pressed down, the valve directs the hydraulic flow to dump back to the sump so that the transmission is effectively in neutral. When the pedal is out, the valve directs the hydraulic fluid through the selector valve that directs the flow to move the 3 planetary gear systems into whatever gear is selected by the gear selector lever. If the tractor moves under power with the inching pedal pressed all of the way in, then either the linkage for the pedal is not working, or the valve that it controls is not working properly.

With the inching pedal not working, you should not try to stop the tractor with the brakes unless the transmission is in neutral. The brakes and transmission will be fighting each other, and you will damage something further.

Anything can be fixed for the right price. A lot of the parts for that transmission are no longer available from the dealer, so you'll probably have to hunt around various salvage yards to find parts.

A standard shift transmission swap-out would also require the rear end be swapped out as well, as the ring & pinion gear ratio in the rear end was different for the S-O-S models than the others, plus the S-O-S had a completely different pto drive setup than the others too.
