P284C Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
The Transmission is responsible for converting the power produced by the engine to movement of the vehicle. Some transmissions utilized electric motors to change gears. If the Transmission Control Module determines that the transmission is not shifting properly, code P284C will be set.
