Default Miata 6 speed trans temp location

I searched the internets pretty hard and couldn't find any concrete info on this, so I pulled out my spare 6 speed and started drilling. Only took 2 attempts!

The one by the drain plug interfered with too much so it got plugged. This one seems to work, but its very tight. Make sure your hole is perfectly centered and the sensor will just barely fit.

Sensor is an Airtex/Wells 1H9. 1/8NPT GM temp curve. Comes from a saturn SL coolant temp sensor.

Is drilling into the drain plug and putting a sensor in that not a good idea? I've seen this done on various other builds (not miatas).

It would work. But the stock drain plug is magnetic. And I don't think drilling that would go down well.
