This is more of a vent than question but man am I frustrated. I have a 14 Ram 1500, 5.7 Hemi. A couple of months ago my dealer replaced the transmission, something wrong with 3rd gear and metal shavings. Under warranty, no problems. The last few weeks I have noticed what I think is a transmission overheating problem. I have been running between Omaha and a location in South Dakota quite a bit recently, 250 miles. That's a mostly flat, straight run. I run 75 in Iowa, 80 in South Dakota. The ambient temp has been between 85 and 90. On one trip 3 weeks ago I happened to switch over to the digital readouts and saw the transmission temp was 230 degrees. That's hot. I was just getting off the interstate and it cooled down quickly. I started paying attention. On my next trip, running 80, pulling nothing, I watched the temp slowly get to 255. I backed off and it cooled down to between 200 and 210. I stopped, got gas, and made an appointment with the dealership. I'll get to the dealership shortly. Since then I have noticed a pattern. She'll run at 194 for about 40 miles, then start to slowly creep up to about 210. It hasn't gone over that since the 255 day, but I still think that's too hot. The dealer looked at it, agreeing that 255 is hot. It didn't throw any codes, btw, I never got a check engine or transmission warning light, and they couldn't get it to over heat, but they didn't drive it for 40 to 50 miles on interstate. It seemed to me that with no codes they are lost. In the meantime, I have a truck I can't trust, and a trip to Sturgis pulling my toy hauler coming up. It's the new transmission, but with no codes they won't replace. Uggg.
