NHTSA Complaint #11592505 — 2022 RAM 3500

When pulling onto the interstate on ramp (45 mph) the truck attempted to shift up when all transmission power failed. The engine ran fine, just no power. I was able to safely pull to the shoulder and park . s Shifting from drive to neutral to park and back to drive still did not resolve the issue. I put the truck in park and shut off the engine . The transmission fluid temp, color and level was ok. I restarted the truck and shifted to reverse with no problem then to neutral and drive. It felt that the transmission engaged and I slowly crept forward. I slowly accelerated and was able to resume speed. No subsequent loss of power has been encountered, BUT the truck now has slippage from 1st to 2nd gear and occasionally 3rd. Had I been on the interstate this has a potential for serious accident incident. This is the first time this has happened. I had bought the truck used and certified from the dealer in Pennsylvania. There is currently 28k miles on the truck. There were and still no warning or codes to indicate a problem This occurred [XXX] 2024. No dealer, tech or shop has looked at this issue.
