Does low oil level result in the case of the gearbox being hotter, or is it just the gears inside?
Would a simple temperature gauge/alarm like an engine watchdog give the driver an indication of low oil?

I wondered about that too. I think that, as the R380 holds so little oil, any warning of temp increase in the housing would come too late to save the box, but that is purely a guess. I wish Dave ( Ashtrans ) would chime in. Maybe I'll email him.Quote:

Is that wiring present in all cars? Of course it will be there in a D2, but what about MA type D1?Quote:

Take a look maybe you find the unused plug around there, a squear(ish) plug with black and purple/black wires in it:
I fitted the V8's TC temp sensor/switch to my TD5 but as already suggested, by the time the housing gets excessively hot from low oil, the gear teeth and bearings may have already been damaged. I also used the gearbox high temperature instrument cluster indicator for my low oil pressure monitor.
Even my manual 84 RRC had the unused temp switch connector, discovered when fording a river that triggered the 'auto gearbox overheating' warning light.Quote:

is that you have very little room inside as the gears are only about
15-20mm away,
A temp sensor may help but as suggested this is just checking the oil
temp, I don't know if this would rise significantly before damage
would occur to the gears if lever was low,

So there you go.
I say again, my idea is to fit an adjustable pressure switch set to minimum there not a temp swicth cos the effect on the warning light would be the same and if there's no pressure in the cooler it's certainly some troubleQuote:
