I have a 2013 Ram 1500 with 65RFE transmission. It also has a Flowmaster 50HD muffler and a K & N intake system. I bought this truck In May and have had a shift solenoid changed out. My problem is that the transmission does not slow the truck down going down the mountain, in any gear including 1st. Every vehicle I have ever owned, slows the vehicle going down the mountain. Is this normal for this transmission? Has anyone had this problem before? I am ready to go back to Chevy, if I can't get this problem fixed.
Hey 1st Ram1500,
We have a TSB that was released back in 2014 that might help--not sure if your truck has had flashes performed or not!
