Hi, this may be a long shot but I’m wondering if there is anything I can do or check to help figure out my trans code P0733. I have a 2021 Ram 1500 4x4 with 5.7 and 8 speed transmission. Shortly after I purchased my truck from a local Dodge dealer I was having issues with it shifting into 4 gear. It finally got so bad engine light would come on and put the truck into limp mode. The only way to drive it was to clear the code. The dealer couldn’t get it to act up and obviously couldn’t see anything diagnostic/computer wise because I had to clear codes to drive it. They did check trans fluid level and said it was clean and full. After trial and error, it will definitely through the code when truck is cold and I go straight to drive. Ambient temp doesn’t seem to matter. If I have to reverse(back out of my driveway) on a cold start then to go drive it seems fine. Is there anything external on these transmission to check? I had a ‘05 Dodge Grand caravan with very similar problems that ended up being a bad trans control solenoid and a broken speed sensors. I’m praying it’s something simple like this, lol. Any help you could give would be greatly appreciated!
