This bulletin applies to 2016-2017 Honda Pilot vehicles. A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60 miles per hour.
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 fluid deteriorates quicker than expected when exposed to intermittent high loads under specific driving conditions. A software update is available to maintain the transmission fluid temperature within the desired range under all driving conditions and eliminate the potential for the judder. Take an automatic transmission snapshot, review the data and confirm that the judder is coming from the torque converter.
If so, update the PGM-FI or A/T system, then flush the transmission per Honda’s requirements. Use i-HDS software version 1.002.017 or later. You cannot apply the updates with the MVCI as a standalone tool. To update the vehicle you must use the MVCI or the DST-I interface in conjunction with the J2534 rewrite PC application on the i-HDS. Refer to the following for program information. This is based on software system PGM-FI. Use program ID and P/N or later.
