On my 7030 once you shift out of high side it willn't shift back up. Any help. T.I.A. Kenny L.

So, what does it do?? exactly, what does it do?....stop moving?? but works fine when oil is cold and then bothers when oil is hot??.......I'd guess leaking rubber seals on the high range piston or a dirty flyball or low gerotor pump flow or all of the above.

Dr.allis, it's after the oil get hot, it try to go but willn't move almost like it is slipping,and works great on low side. Thanks again Kenny L.

If the floor button stays down and it slips in high, I'd guess you have internal problems.......don't know the history (hrs) on it and it needs some gauges installed to verify pressures to be sure.
