When did it start happening ( miles)? I had it happen one time for sure @ <100 miles and not since. Im at 1500 miles and wondering if its a lroblem to come or if my solenoid justCurrently, it has happened about 7 times since Monday (so in five days of driving and I am about 220 miles on the ODO. When it happens, I just shift into R and then back to D, and it works fine. I agree, it doesn't feel/appear to be electrical, but mechanical, hence why a code wont appear. I have a case open with Ram, and they have already reached out and said we would follow up after my dealer visit on Wednesday 1/2/19. Looks like the only verified repair, is a new valve body (or in this case a transmission). Its not a big deal to me as long as shifting it into R and then back to D works.
stuck one time since it was new.
