Most Reported On
P17D6 is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Transmission Clutch/Engagement Fault.” P17D6 is a manufacturer-specific transmission code (documented in GM 10-speed service material, e.g. the 10L80/10L90, and also appearing on some Audi/VW dual-clutch transmissions) that generally indicates a clutch or gear engagement fault within the transmission. It typically means the transmission controller found that a clutch is not applying or releasing within expected limits, which may produce slipping, harsh or delayed shifts, or a reduced-power/limp condition. The precise meaning is make- and transmission-specific, so confirmation requires the manufacturer's service information.
