What happened when owners saw P0871?
6 of the 6 reports, spread across the models above, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.
While entering the interstate highway and accelerating to merge into traffic the transmission would not shift properly and check engine light came with code p0871. I could not fully control the speed to keep up with traffic due to the erratic shifting of the transmission and was nearly rear ended by another vehicle also merging into traffic. This could have caused a multi vehicle accident at highway speed of 65 MPH. The p0871 code is transmission fluid pressure sensor / switch c circuit range/performance. There have been previous recalls with this transmission for the same problem but my vin was not listed. Transmission would not shift properly until code is reset with scan tool.
…The codes that my car had thrown were the codes that appear in Special Coverage [XXX] (P0871, P2714, and P0871-00). These were the same codes that were thrown at the time of the original replacement in 2016. Upon doing a full diagnostic of my vehicle, the dealership had agreed with the prior codes listed. However, GM is denying my claim of this coverage due to my reconstructed title. After looking at GM's own website where I had to enter my VIN, the coverage for this adjustment says it is active, and will not expire until my car reaches 120,000 miles, or until January 25, 2025 (10 years after it was placed in service). My car is currently at 113,760 Miles. It does not say anywhere that a…
…The truck later developed code P0871, became undriveable, and was towed back June 1. The original transmission ultimately failed. The dealership then installed a Mopar remanufactured transmission. I picked it up June 13. Within roughly 600 miles, it developed substantially identical symptoms and failure patterns, including P0870 and P0871, limp mode, and another major transmission failure. It was towed back June 24. The dealership later found the overdrive clutch had disintegrated and metal was present in the transmission fluid. The failed remanufactured transmission is now being handled under its Mopar warranty, and the dealership is looking to install a third transmission without…
vehicle intermittently sets check engine light for code p0871 and causes truck to go into a limp mode and a 4th gear start only. I have notice online this issue going on for years on Ram trucks with no recall. The light will go off and store code but dealers will not address if light is not on. If truck set code with not at moment effect I could see, however what happens can occur during driving and feel it creates an unsafe condition.
MY CHECK ENGINE LIGHT CAME ON WHILE DRIVING AND WENT OFF AFTER ONE DAY. IT CAME ON AGAIN 3 DAYS LATER WHILE DRIVING, AND AT ONE POINT I WAS NOT ABLE TO ACCELERATE FROM A STOP. A MECHANIC HAS DIAGNOSED THE ERROR CODE AS P0871 AND ALERTED ME TO GM BULLETIN PIP5521 WHICH STATES MY ENTIRE TRANSMISSION MUST BE REPLACED, DESPITE THE CAR ONLY HAVING 56,000 MILES ON IT. THIS IS A KNOWN ISSUE BY GM WHICH PRESENTS A SAFETY HAZARD AND THIS CAR SHOULD BE RECALLED. MY CAR IS SLIGHTLY OUT OF WARRANTY AND I'M ATTEMPTING TO GET GM TO FIX IT UNDER A GOOD WILL WARRANTY.
The transmission in my truck has been having problems starting on 9/25/18. On 7/21/22, Grey Chrysler replaced the solenoid in the trans and also did an update. When I brought truck back after the same code, PO871, was thrown again on 08/30/22, I was told the warranty company couldn’t recreate the problem so they would not be fixing my trans. This is the same trans that is in the 2019-2022 Ram 2500 trucks and has a recall on it for the SAME problem.
P0871: questions drivers ask
What does code P0871 mean?
P0871 is a generic OBD-II powertrain code. Its standard definition is "Transmission Fluid Pressure Sensor/Switch 'C' Circuit Range/Performance". 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 P0871 most often?
In NHTSA owner complaints, P0871 is mentioned most for the Ram 3500 (3), Chevrolet Spark (2), Ram 2500 (1), across 3 models and model years 2014 to 2019. Popular models collect more reports because more of them are on the road.
Is there a recall for code P0871?
No NHTSA recall text names P0871 directly. 3 recalls on the cars that report this code concern 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 P0871?
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.
How this page was made
CarHooq read the text of every owner complaint filed with NHTSA for 19 US and European brands (model years 2012 onwards) and picked out the diagnostic trouble codes owners wrote down. This page lists every mention of P0871. The definition is the generic SAE J2012 wording; a carmaker may use the code slightly differently. Nothing here is a diagnosis. More answers: the fault code FAQ. Data: NHTSA Office of Defects Investigation (public domain), retrieved November 9, 2026. How CarHooq reports are made.
