1989 JD 4255 MFWD

Dave Graeve The powershift on this tractor, when the trans mission gets warmed up it works fine but if you stop and put it in neutral and then try to go again there is nothing, so I put it in park ref up the engine put back in gear And every thing works fine again I have changed the tansmission filters and power washed the oil cooler the linkage is free, I took the council apart and cleaned all the dirt away from the boots,I lubed the shifting quadrant so it is working freely talked to 2 mechanics and there not sure what it is? If anyone Knows Please advice Thanks Dave
Mike Sounds like a valve sticking in the shift housing. It will require some diagnosing of all the pressures.
Dave Graeve Thank you Mike for the advise, what I can't figure out is why everything works fine until the oil is warmed up.Tried adjusting front linkage yesterday as advise by my mechanic, will see if that made any difference when fields dry up again
Dave Graeve The Problem with my 4255MFWD Power shift was a chunk of something in One of the shifting valves on the external shifting case. It was nothing serious. Dave
