Hello all. I have a 2018 Laramie 3500 and past two times towing heavy I have had a P0868 code come up. I took it to the dealership and they wanted to keep it for over a week. I can't be without the truck that long. So I had them check the fluid and it was barely in the lower safe line. I told them to top it off and if it comes back I'll have them hook it up and diagnose it. The truck was purchased brand new with 19 miles. I have a little over 21000 now. Never beat on it. I want to delete with Ray from DRD tunes but am sceptical about the dealer warranty BS. Any one think that code is a fluke? Just looking for advice. Had diesel my whole life. This is the first Cummins powered rig and my first automatic. Is the 68RFE decent after the 12 years it's been around. Can't afford to bite the bullet on a built rev Max yet.
