Our certified mechanics come to you · 12-month, 12,000-mile warranty
P0876 is a diagnostic trouble code (DTC) for "Transmission Fluid Pressure Sensor/Switch D Circuit Range/Performance". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
The storage of a P0876 trouble code signals a problem with the transmission fluid pressure. When this happens a P0876 trouble code is stored on the Powertrain Control Module (PCM) and a Check Engine light illuminates. In addition to the P0876 trouble code, the PCM might also store a P0875, P0877, P0878, and P0879 code.
When the transmission fluid pressure is higher or lower than the manufacturer's specifications, a P0876 trouble code is stored and the Check Engine light illuminates.
Some of the common causes for the storage of a P0876 trouble code include a low transmission fluid condition, defective high pressure pump, and a malfunctioning transmission. An overheating transmission, bad transmission temperature sensor, and bad PCM can also cause the storage of a P0876 trouble code.
A clear symptom of a P0876 trouble code is the odor of overheated transmission fluid present. Smoke issuing from the area of the transmission is also a strong indicator of this code. A final sign of a P0876 trouble code is failure of the transmission to engage and a slipping transmission.
Diagnosing a P0876 trouble code requires the mechanic to have an advanced scanner, digital volt\ohmmeter, a manufacturer's wiring schematic for the vehicle with the trouble code, a manual pressure gauge, and a hydraulic pressure diagram. Once all of the necessary tools are gathered, the mechanic should perform the following steps:
One common mistake made by mechanics when diagnosing this trouble code is assuming that the code is caused only by a transmission fluid leak when in actuality the low fluid condition has allowed the transmission components to suffer damage. Another mistake is for a mechanic to rebuild the transmission when it is not needed.
To prevent serious damage to transmission components, vehicle owners need to have a P0876 trouble code diagnosed and repaired as soon as possible. The longer a vehicle owner waits to get it repaired, there is more of a chance the transmission suffers from slipping and even failure.
Repairing and clearing a P0876 trouble code is a multi-step process that requires the mechanic to perform the following:
Start by rebuilding the transmission if it received damage from a low fluid condition. The mechanic should also install a new torque converter.
While repairing the transmission, the mechanic should also fix any leaks.
Replace the hydraulic pressure pump if faulty.
Replace the PCM, making sure to reprogram the new PCM.
