Well mine popped 3 codes, went to dealer, couldn't get me a appt for 2+ weeks, they pulled codes just because I asked, but I knew what codes it threw since I have a obd2 bluetooth adaptor. So 3 days later all codes cleared, 3 days later threw a shift code again but didn't get stuck in 4 and went off next day. Finally got to the dealer for the appt, but, nothing they could do since codes reset. Now, about 3 weeks later I was sitting at stop light, dry day(no rain) started to pull away from light and felt a clunk in tranny, stuck in 4 again but no cel light. Stopped, restarted truck, was normal again. Week later, on freeway, noticed truck felt odd, wouldn't let me manually shift, no cel, then after a few minutes was normal again. I only have around 45 days until 5 year power train warranty expires, any suggestions, should I call Ram customer service? Dealer says, without current cel on, there's not much they can do.
