I have a 2018 RAM 3500 Cummins. Mine is the mid level diesel motor so I don't have the Aisin transmission. I have 33,000 miles on it and It has pretty much been trouble free as far the engine and transmission goes. I really like this pick-up even though I have been a GM guy my entire life. I did have an update on it computer when the rear view cameras went wonky recently. I am experiencing hard idle at start-up, but it smooth's out pretty quickly. It didn't do that when new so may need to be checked out. It came with a too small fuel tank and doesn't get the mileage a diesel should. 6-8 pulling a 28ft camp trailer and 16-18 empty depending on what tires I have on it.
