AFFECTED VEHICLES

Year Model Trim VIN range
2012 RL ALL ALL

 

REVISION SUMMARY

Under AFFECTED VEHICLES, moved 2014–15 RLX to 16-065, 2014–15 RLX: Judder from the Torque Converter Lock-Up Clutch because a software update is available to address this issue.

 

BACKGROUND

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.
