Def get a aftermarket trans cooler and thermo fan and ideally move it away from the radiator.

Upgrade the stock clutch fan to a heavy duty item.

Make sure you have the best aftermarket coolant possible (factory Mopar stuff is garbage) suitable for your 2011+ CRD.

After the above, you shouldn't have any overheating issues unless there is something wrong or faulty. And being a 2011 model you would see temps between 95-105 degrees towing and this would be acceptable.

Also monitor your coolant and trans temps via a OBD2 reader of your choice for realtime figures. The dash is too vague.
