Normal Transmission Oil Pressure
In view of the recent ditching , I would like to compare notes again on the normal indicated transmission oil pressure. On the RFM it mentioned that Min Trans Oil Pressure is 0.4 bar.so it implies that anything above that figure is normal. However in the MGB drawings it says MP light comes on if the sensor senses a pressure of less than 3.7 bars. I have not seen many 225 flying with a MGB oil pressure of more than 3.7 bars on the MGB oil pressure gauge. I believe the MP light does not come on because the MGB oil pressure gauge taps its pressure after the oil has been splashed on the gearbox whereas the pressure switch for the MP light is just after the MP.
Any inputs on your indicated MGB oil pressure is appreciated
