What do you mean getting hot but in operating range. If its in the operating range its NOT hot. Normal operation 190+or-, when climbing with lower gear and 4500 RPM to around 200 + or- then the fan kicks in. you can hear it, soon temp starts cooling with trans temp lagging a bit. Need more info, sounds normal.

The 3rd time the problem happened after running a total of about 850 miles (after the thermostat was changed out) without any increase in temperature including going up and down hills. On that day the temperature after the motor warmed up stayed normal for about 3 hours running at 65 to 67 mph with the rpm running about 2200. This included going going up and down hills with the rpm increasing from about 2200 to 3500. Going up a hill no worse than some of the others, the themperature started to climb and appeared to be still increasing. It got to the upper white mark eventhough I slowed the motorhome down to decrease the rpm down from 3500 to 2200, before I got the temperature to decrease very slowly back to normal, after that 1st occurrance the temperature would start to climb everytime the rpm increased to 3500.
