Transmission judder, hard shifts and torque-converter failuremajor
2017 carries both transmissions and both of their weaknesses. On the 6-speed (lower trims, lever shifter) a lockup judder appears between 20 and 60 mph; Honda's bulletin traced it not to a bad torque converter but to transmission fluid that deteriorates faster than expected. On the 9-speed (higher trims, push-button shifter) owners report violent jerking, shuddering, and torque-converter failure — one documented a 9-speed failure at 107,593 miles repaired for $6,229.91 at an independent shop. The fix path is a fluid-injection (PGM-FI) software update plus repeated fluid exchanges, escalating to a torque converter or transmission. Drive it through all gears and inspect the fluid and service records.
