Customer Letter	2017-10-21. Service bulletin. Customer letter - Our records indicate that a PRODUCT UPDATE has not been completed on this vehicle; refer to the address card for the affected VIN. There may be a judder from the torque converter lock up clutch felt while driving between 20-45 mph.
A16-060	2017-07-31. Service bulletin. Service bulletin - A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60mph. The problem is typically diagnosed as a bad torque converter. American Honda investigated the judder and found that the torque converter was not causing the judder; rather, it was caused by deteriorated transmission fluid. The transmission fluid deteriorates quicker than expected when it is exposed to intermittent high heat loads under specific driving conditions. American Honda is working on a software update that will maintain the transmission fluid temperature within the desirable range under all driving conditions and eliminate the potential for this judder. American Honda will revise this service bulletin when the software update is available.
