I have my transmission temperature sensor in the same port you are using. I see about 40-60 degrees over ambient. For me, that means my transmission is running around 100° since we are in the worst part of winter now. I used to monitor engine oil temp, but found the numbers were always right on with what the EOT sensor in the HPOP was reporting to the PCM, so I changed that to engine oil pressure. When I was monitoring temp, it was always within 5 degrees of ECT once the engine warmed up. For me, that was 180° - measured at the port next to the oil filter.
I would contact your gauge manufacturer - something is seriously wrong either with your installation or your gauges.

I wonder if clouds ever look down on us and say, "Hey, look - that one is shaped like an idiot!"
