Ok I checked out the HD 11 EP TRANSMISSION TODAY .It will move forward and backword . But it will lock up like it is in two different gears forward and reverse. you can move shift selector just a little . And it will start moving again. It has had new Clutches put in transmissions. But did the same thing they said the selector had been rebuilt a.the hoses look like they need replacing. Just trying to give as much information.as I can also said the pressures checked out ok. Just wandering if any one has every ran into this problem. Going to try to load it on trailer tomorrow.it seems to become worst when hot. Thanks

It almost sounds like the valve body is warping hot or has a internal crack opening under heat and allowing fluid to enter both selections. My 7G powershift has never done so and cannot remember ever seeing this on another machine.
