When I turn off my Case 450B track-hoe with the front of the tractor higher than the back, the trans pressure does not come up when starting again after just a few minutes. If I use the hoe to raise the back the pressure will return after several minutes. Can anyone help.

Did you ever find out what the problem was? I've got a 450B crawler that does the same thing, and was wanting to know the diagnosis.

Either you have a smal pin hole in the pickup hose/tube and letting the pump get air or the pump is just about lived it"s life. A small pin hole will let the pump suck air but will not leak fluid.

FYI

If the pump locks up it could break your cam.
