Tractor Repair: Transmission Pressure, hay bails, pressure sensors

Question
Hello there, I have a CASE 1070 with a loader on it. When I am removing snow, moving hay bails or anytime that I use the hydraulics continuously my transmission pressure jumps sky high. Can you please explain to me what I am doing incorrectly or what I can do to remedied this.
Thank you,

Darin

Answer
I am going to need more information. How do know that the transmission pressure is high. Is the filter blowing off? Is the warning light coming on? If I remember right we had problem's with the pressure sensors going out. Check on the sensor  on the trans valve and make sure it is not leaking oil out of it. If it is, change it should solve the problem. If this is not the case and you have a pressure gauge in your trans pressure port I might have to think about that. Follow this question with a follow up with more details.
