Power Shuttle problems

[scanderson]

I have a 2014 1643 Massey Ferguson Power Shuttle. It suddenly just started going forward only even in the neutral position. When I go to reverse the tractor will stop like it's in neutral. The micro switches at the shifter check good. If I unplug the connecter at the solenoids at the valve the tractor will not go in any direction do guys have any idea?

I don‘t know that transmission, but are you sure there is no mechanical linkage to the transmission?

If you disconnect all (both) of the solenoids you could verify if you are getting a voltage signal to them at the proper times.
Also both solenoids should ohm out the same often 5-8 ohms for the windings.
