Hello,
I have a 2015 Dodge Journey 8500 miles. A few weeks ago I was towing a trailer max weight was no more than 1600 lbs . Max tow weight is 2500 lbs. I noticed at my trans temp went up to 263 . The coolant temp gauge under the tac read one line before the H . The oil and coolant were between 245-255 . Pulling up a small hill. When the ground returned to level the temp went down 10 min later. Now on the same road this time not towing the trans temp went to 222. I am not a mechanic but I know this is to high. Any ideas why in a new car .
Thanks in advance
