Civdiv99, I have a diagnostic tool to read the transmission temperature sensor. If this is helpfull to you, I could connect my laptop tomorrow while going to work (30 min highway drive) and let you know the max I read.

I read somewhere that the ZF fluid is expensive because it is formulated to be non-conductive since many electrical connectors are submerged in the fluid.
I would be curious though to take a measurement between the ZF stuff and M1, just to see.
