My Powershift Wont Go Into X Gear

There are really 2 common things that can cause this -

1- EASY
Be sure that the linkages are not just wore or our of adjustment- especially if it wont go into the first or last gear on the selector. It could be that the valve is just never actually reaching that gear.

2- NOT EASY
There are small seal rings on the shaft that the clutch packs are on. Those rings keep the oil going to the right clutch pack depending on which gear you are in. If any of those rings leak there will not be enough pressure to keep the selected gear's clutch pack engaged. The ring for the gear's clutch pack that you are missing could be leaking.
