My transmission was damaged by a pothole and replaced with item R890720AG in September 2018. I was driving with my family and my transmission failed with code Po944 among other transmission failure codes; on Monday January 16, 2023. While driving on the freeway I heard a weird grinding noise. The vehicle suddenly without warning slowed down. No matter how much I pressed the gas it did nothing. I tried to pull over to avoid traffic. The vehicle kept at a slow pace. Finally as I approach the edge of the road it stopped. I had to then push it to safety and call for a tow. The code P0944 is the same code that is with the recall S44. I understand that my vehicle is not part of the recall S44 but…

However, the VIN number for my vehicle doesn't show up when searched. Given the type of transmission problem we're experiencing, the assembly month/year, the engine too, can someone be assigned to investigate if my vehicle should be included in the recall? It has the symptoms…

P0944: questions drivers ask
What does code P0944 mean?
P0944 is a generic OBD-II powertrain code. Its standard definition is "Hydraulic Pressure Unit Loss of Pressure". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 3 car models.
Which cars get code P0944 most often?
In NHTSA owner complaints, P0944 is mentioned most for the Chrysler Town and Country (4), Dodge Grand Caravan (3), Dodge Journey (2), across 3 models and model years 2013 to 2016. Popular models collect more reports because more of them are on the road.
Is there a recall for code P0944?
No NHTSA recall text names P0944 directly. 1 recall on the cars that report this code concerns the same component owners name most (Power Train); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P0944?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
