2500 4X4 diesel engine oil temp

[sb2013]

what is everyone seeing on average healthy oil, Trans and Coolant temp?

MY 2016 shows the engine oil and coolant at the same temp, 180 degrees, +- 2 degrees or so of each other unloaded. Trans around 168. Hauling heavy (13,000 Lbs) around 195 - 210 for both engine oil and coolant. The trans shows 172 - 174.

This was near the summit of the twisty, east bound Monarch Pass, CO climb on a warm day. Pulling an 8K enclosed trailer, 18 Ram 2500 Cummins. I was not taking it easy. Such a stress free truck to pull with.

Interesting, my 2021 6.4 in the 2500 runs Oil and Coolant at about 212-4 F running empty, Transmission about 168. Ambient air temp was 70 F. Interesting to see the Diesel transmission runs very close to the same temperatures.

There is a thermal bypass that regulates the trans temp to stay right around that ~168 mark. Of course it can go hotter if being worked real hard on a hot day.

Oil temperature and pressure on the Cummins is a calculated value, only sensor is the low pressure switch to prove there is some pressure (> 7 - 8 psi)
