2016 trans temp

[Micsol]

I'm trying to find out if this is normal. My 2016 2500 transmission seems to run warm. The truck only has 3800 miles. But on a recent trip of about 100 miles the trans temp on the evic was running 201-203 with the clutch fan coming on constantly, about 70 degrees outside temp and engine was only 195. *This trip was empty highway cruising. On a short 10 mile run it will get up to 190degrees. Is this normal it seems higher than the temps I got on my 2010 ram. *The temps never climbed above 203 even climbing through the mountains they just seemed to hover there. And like i said this was empty. I'm concerned about the temps ill get when I start pulling my camper. And I bought the truck last fall so *this is the first I've ran it in warm weather

So you have a 68RFE transmission?

68rfe. 6.7 Cummins

That's what I have in my 2007.5. Not towing I am about 150deg in the summer. I tow a 9000 lb camper and am not seeing anything near what you are seeing solo. I am sure someone on here will have some ideas as to what's going on and if there is a problem or not.

Running at 200+°F when cruising on the highway (empty) is NOT normal. You may have a stuck Thermal Bypass Valve (TBV). This is an H-shaped block of aluminum in the middle of the cooler lines, usually just in front of the transmission. Check the temp of the lines once your truck is hot (180°F or higher). If the two lines between the TBV and the cooler are BOTH cool (while the two lines between TBV and trans are both hot), then your TBV is stuck shut and should be replaced.

So my basically new truck already has a problem

Problems happen all the time. Listen to the advice you are getting.*
