    New Holland Tm135. Warning light for transmission oil filters blocked is flashing, but NO alarm.
    Only done 80 hours on these filters. Changed them this morning for new ones, filtered out oil out of them and seems clean.
    Symbol still flashing with new ones but still NO alarm.
    What is the issue please?

    Check filters again, almost always brakes worn/wearing out. Might be lucky and it’s the pressure switch/sensor thing.

    Pressure switches often fail on mine and cause those symptoms, quick easy cheap replacement job.

    Edit- when the light starts flashing I usually pull the wire off the sensor so it doesn’t get on my nerves for the rest of the day.

    Then get a new one screwed on the following morning

    As Drillman says there is a pressure switch on the housing that the hydraulic filter spins on to, it is most likely that as we have had them fail on 2 TM's

    Brakes were my first concern but changing filters made no difference to the light flashing.

    Had a rummage round and now pulled the wire off the sensor.
    Thanks @melted welly @Drillman @YELROM
    Will pick another up somewhen, hedgecutting again now :)

    Have to be a bit careful because I thought these filters had a bypass on them when blocked. Someone once said they also suck all the snot out when bypassing but I don’t know if that’s true.
