I appreciate the reply, Stephan. I was asking about the engine oil temp versus the trans oil temp. I don't have EGT or boost gauges yet, but I need to install some soon. Both temps never get above 210 based on the in-dash gauges, it just concerned me a little the oil temp stays around the 210 level for the majority of the trips even when running with no load.Are you asking about an intercooler for the turbo Sam? If you are, do you have pyrometers on your exhaust? Also, are you asking about engine oil temp, or engine coolant temp?
As for the trans temps & engine oil temps being the same, mine aren't, but I have an aux trans cooler on it. If yours has the radiator trans cooler, then it may run the same unless you're towing, then your trans temp could run a little hotter.
