First time diesel owner

We finally brought it home today. A week and 1/2 ago we drove to Martinsville, VA to purchase our 2006 Ram 2500 CTD. After we left the dealer, we had major problems. It was towed back to the dealer and after their troubleshooting, the transmission ate itself. They really worked with us on getting a better transmission and torque convertor. I even shipped them Amsoil to use. Today I met their delivery driver in Bowling Green, VA. When we test drove it, I noticed the temperature gauge would float over 200 deg. I guess my main question is what is the normal operating temp? We plan on using to pull a travel trailer. And I don't want to ruin the new transmission. Need some ideas on what to look for and possible repairs. Any help would be appreciated.

Your truck should run right at 200* or slightly less. It has a 190* thermostat unless it has been changed. Anything above that temp you should hear the cooling fan roaring and should cool down instantly. The electronic cooling fan clutch is sometimes problematic on those models. I would first check for excessive debris in the core of the radiator and for broken wires to the fan clutch.

both my 05's and my 06 always ran just a touch over 200, just like in the picture.

Just shy of 200 on mine.

Was wondering. We plan on bringing our travel trailer home next weekend. There are afew stout hills between Harrisburg and Baltimore. I guess with a new truck, it'll be a learning experience......

That looks like a typical temp reading.

Normal

Another question.... I know about putting it tow mode, when pulling a trailer. What excately does that do??? Thanks for being patient

locks out overdrive

Raises the shift points and shifts harder. I use Tow/haul ALL the time.
