JD6410 remains in FWD

[Zebrafive]

Ok, my friend from USA.
4x4 is now working!
Adaptor and gauge gave reading of 0 bar.
Toggled rocker switch and reading remained 0 bar.
Checked reading at solenoid and 0 volt.
Pulled toggle switch out and fiddled wires, intermittent 12v output.
So, replaced it with new rocker switch and voila 10bar(145psi), and tractor popped out of MFWD!
Many thanks again.
Found Priority valve, pls check my photo for correctness.
What should the pressure be at each port.?
Also, on the front cover on transm are switches for LOW OIL PRESS, LOW OIL TEMP.
What are these trigger values?
What should the operating temp and pressure be?

May I pls know your name?

Your picture is correct, all ports are labeled correctly.
When I have more time, I'll get you pressures for these


Rule of thumb is operating temp will be 80-100°F more than outside temp


Name is Robert

For the test ports on the priority valve. Run engine at 1500rpm


LS (Load Sense) Valves in neutral, steering not activated 29-87 psi. Valve (rockshaft, SCV) activated 2900 psi


Steering Steering not in use 145-218 psi. Steering at a stop 2540-2730 psi


System Minimum (no valves, rockshaft, or steering in use) 406-479 psi
Maximum, SCV engaged 2900 psi


Which Transmission??? It's system pressure is not the same as measured at the priority valve.


Normal temp range is 100° - 150° F, so I assume low temp triggers below 100°
