when you lift the pump sounds like its running in bypass it will lift the first stage very slow and wont have enough power to lift the second stage
also at the same time tilt is completely inoperative even though the pump runs with tilt request
(sounds like its in bypass again)
then it will work fine then the prob comes back
cust claims resetting the key fixes it but that does not seem to be the case (very random)
my shop guy took out the valve body and cleaned it out also put a new filter in with no change in problem

i tried swapping relief 1 (lift) and 2(aux) since they carried the same part # but there was no change
no codes so i think its a stuck valve but not sure which 1 since if lift select was stuck then it would lift when i request tilt and if the tilt valveswhere stuck then i probablay wouldnt have a problem with lift
any heads up would be great
thanks
