970 Case Powershift issues

[JBobbe]

My 970 just stopped moving. The transmission pressure dropped to zero. The range shifter works as I can tell it is engaging. No hydraulics. I let it sit overnight Istarteditu, hydraulic worked for a bit and it stopped again. The powershift was rebuilt before I bought the tractor. I spoke with the mechanic at the dealership who did the work so has less then 500 hrs. The hydraulic controls had to be replaced about 18 months ago. Hydratran has always been used I had a mechanic out today. suspicion is the hydraulic pump went out. Questions: The fill dipstick/filler tube for the hydraulics is on the back. How does that relate to the plugs on the side of the transmission (Possibly pipe plugs replaced the bubbles where you can see the fluid levels) where you can check the fluid leveL? It's my understanding the fluid for both the powershift and hydraulics are the same reservoir? Comments or suggestions appreciated.

sounds like you are low on oil and went down hill and she sucked air,, transmission and hyd oil are the same keep it above the top glass when setting Level and after the unit has been shut off for a 1/2 hour or so, I like to check them cold as you get a better reading, keep the sight glasses clean so you can see through them easy, when running at idle and setting level if you see the top glass is half full you are fine on oil,, you will Not see oil at the fill point at any time as level is well below this point
