MF 6180 hydraulic pressure light

[Cowcorn]

The hydraulic pressure or trammisson light came on on our 6180 today while ploughing. I changed the filters which did not appear to be in bad shape but the light remains on . The tractor diff lock and pto are not working but everything else is fine
When stopped for lunch it was out whem we resumed but re appeared shortly after and lost diffs. Any advice ???
Thanks in advance .

It might be a faulty pressure switch but better to test the pressure to see whether it's an electrical or hyd pressure fault.
