P0871
Transmission Fluid Pressure Sensor/Switch "C" Circuit Range/Performance
DTC P0871, sometimes indicated as P087100 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the transmission (gearbox) causing transmission fluid pressure sensor/switch "c" circuit range/performance.
The Transmission Fluid Pressure Sensor/Switch "C" Circuit Range/Performance message is usually caused by a problem with the transmission fluid pressure sensor or switch.
If the sensor or switch is not working properly, it will not be able to accurately measure the transmission fluid pressure. This can cause the transmission to shift gears erratically or not at all.
The most common solution for this problem is to replace the transmission fluid pressure sensor or switch. However, if the sensor or switch is not the problem, there may be something else wrong with the transmission.

2014 CHEVROLET SPARK with 56306.0 miles
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.

Driving from sj to la, calif. 200 miles into my journey with wife and 3 kids, pulled off highway for gas. Slowed down and noticed the wrench and check engine lights on and car would only go 10 to 15 miles per hour and revved at more than 3000 rpms. The car clunked hard when put into drive or reverse. Turned off the engine, several times and restarted. Sometimes fixed problem, other times did not. I had car towed to hanFord, california, and then again to los angeles-another 198 miles to Ford dealership. I had to rent a car and drive the rest of the way to la and drive back - 198 miles-to hanFord-to return the rental car. I tested the car a few times in hanFord and when it was at the Ford dealer. From a cold start, the car worked fine. Drove and shifted well with no problems. But once the car warmed up, it went back into limp-mode, clunked hard when you shifted into drive or reverse, and would go only 10-15 mph at 3000 or more rpms. The dealer test drove it and had the same result. The dealer got codes P0701, P0871, and P0961 and said that meant the transmission had internal problems. They said they called Ford engineers who told them the likely problem was when the transmission fluid warms up, it is not properly circulating due to leaks in what they called two variators inside the transmission. They quoted the cost to replace the variators as $3600 for parts and labor of $1200 for a total of $4800 and that is more than the cost to replace the transmission for which they quoted $4500. So they replaced the transmission. After starting, they found a broken transmission mount so they replaced that for another $250 (part only - no labor charge). I test drove the new transmission yesterday. The car no longer goes into limp mode and drives nicely except after it warms up it clunks hard into drive and reverse and wines in reverse gear. Not taking car till fixed properly.
