7410 hydro. problem

Joe Low charge pump pressure when you frist crank tractor, pressure at test port on filter spike to 90lbs. but then drops to 12 at idle & 19 full
2350 rpm.

ross First thing I would do is change the filters and cut them open to see if any metal or forein material is in them. I think there is a pump that supplies oil to the main hydraulic pump and other parts of the trans. Plug a pressure gauge into #1 SCV and see what you get. Typical pressure is 2900 psi. Sounds like your main hydraulic pump is shot.
