What are N O Ts for various oils in a TJ

Hi All,

Just curious, what are normal operating temperature in centigrade (okay, I
can live with the Funny measure too) for engine, automatic transmission,
transfer case and differentials? I have been trying to find out, but there
is nothing much available.

I am putting in a temperature gauge for the auto transmission and was just
curious about other temperatures. I was getting the Dalcon gauge with dual
scale100-320F/60-160C smart gauge which has a LED indicator set at 240F to
warn conditions are going south quickly. I wanted C only as gauges on a TJ
dashboard in New Zealand are in centigrade.

Thanks in advance.
