The powershift runs off the main pump, it just has a big flow divider in it, but the part divided to the power steering also goes to the powershift, and the powersteering is fine. Also, it has been the exact same way for the past 4 years I have owned the tractor, just got a fresh fluid and filter change, which also included cleaning the strainer, and nothing changes. If I shift back to 2nd, then to 3rd pretty quickly (in neutral or a low gear... not road gear) it shifts what I would think is normally. The thing is the pressure just dropps off in that circuit when I shift and leaves the whole transmission hanging with no pressure for a split second, then all of a sudden it gets pressure back and works. That's why I was thinking it was a sticking valve, because that is what I saw when I hooked a pressure gauge to the powershift test port. It's not a lack of flow, because then if I cut the wheel very quickly (remember, steering is on the same circuit), the pressure remains constant in any gear range, PTO engaged or disengaged. My guess was a hanging 3rd gear spool, modulating spool, or pressure control spool. I'm not completely ruling out faulty seals in the powershift, but it just doesn't seam likely enough for me to not try something else first, like running a cleaning agent in the transmission to try to clean any gunk out of the powershift valve body.

I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the
