Code P17E8 MINI Description

The P17E8 MINI code refers to Ratio Monitoring Shift 3-4. This code indicates that there is an issue with the transmission's ability to shift smoothly between the third and fourth gears. The transmission control module (TCM) monitors the ratio between these gears and if it detects a discrepancy, it will trigger this diagnostic trouble code (DTC). This can lead to poor performance, decreased fuel efficiency, and potential damage to the transmission if left unaddressed.
