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'm still thinking that the pressure switch connected to the built in transmission temp warning would be enough, especially that the wiring should be already there
AFAIK the M reg auto D1s aslo have the transmission temp warning so it's a big chance for the wiring to be there unused on manuals, but the warning lamp it's certainly in the instrument pack so it can be joined if the wiring is not there
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.
Got a reply from Dave Ashcroft:
Hi,
A float switch would be ideal in the filler plug hole but the problem
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.
