My 1070 is starting to lose trans pressure when the rpms go above 1200. It stops moving and the steering gets hard when it moves. Do I have a pressure valve open or what could be my problem. Please Help

It sounds like you have a suction leak feeding the pump. In a shop the tech would run a pump flow test to check the pump and then a flow test to detcet promlems in the RPS tranny.
You probably don't have the necessary equipment to do that, so I would first take the pump off the rear of the tractor, and check the quad ring that seals the pump intake to the rear PTO housing. If that is good, I would then pull the rear housing and check the suction screen, in the base of the tranny. If it is plugged with fiborous material, I would be examining it to determin where it came from.
If you need to pull the rear housing check back here for some tips, that will save you some grief during the R&R process.
