B160662017-08-31. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Service bulletin - After the software update, some vehicles based on how they are driven (extreme conditions) may still experience ATF deterioration after updating the PGM-FI system and the shudder may return. The problem is typically diagnosed as a bad torque converter (TC). There is no damage to the TC, but because the ATF has deteriorated, it needs to be changed even though the ATF Service Due message has not appeared. Make sure the software is updated by referring to the INSPECTION PROCEDURE.
B160652017-08-31. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. Service bulletin - A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60 mph. 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 and the transmission is not damaged by this judder. The judder 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. A software update is available to maintain the transmission fluid temperature within the desirable range under all driving conditions and eliminate the potential for this judder.
