Got a 2017 RAM 1500 SLT (Quad/4x4/Pentastar) about a month ago now. Been doing some work to it little by little on the weekends, and one thing I'm paying attention to now is the temps.
Right now it's 80% humidity and in 84 degrees F ambient temperature, I noticed the transmission fluid temp floated around 184-188F just driving the speed limit, no hard accelerations, no towing, and on flat ground. I've read that it should actually be 175F for best life. I have a few questions about this:
1.) Is this a safe/normal range for those conditions on this truck? If not, any suggestions of what to inspect?
2.) When the ATF is about 175, does this mean that the fluid just needs to be replaced more frequently, or that the transmission parts degrade faster? or both?
3.) If I wanted to, would it be useful to upgrade or replace my transmission cooler? I do plan on doing some lighter towing (~4000lbs).
I realize the other possibility is that the sensor is a little inaccurate... I notice that my engine oil temp sensor fluctuates by 2 degrees every few seconds so I expect a little bit of inaccuracy there too...
