The original subject was "4250 powershift".
Finally got around to fixing the tractor that was slipping in odd gears. It ended up the B-hi clutch was toast. Looked like some of the piston seals were leaking. Fixed all that and put it back together. The system pressure is still 162. I'm going to shim it to get the pressure up. One thing that seems odd is that the lube pressure drops from 20 to 10 psi for a second or two when shifting from 11 to 12 and 13 to 14. It goes right back up but takes a little bit. Before it was dropping to 10 psi in 12, 13, 14, 15 and not going back up to 20 psi. Is this a problem?
