*REVISION SUMMARY
Under BACKGROUND, information was added.*
BACKGROUND
Product Update: PCM Update for Lock-Up Clutch Function
*A judder from the torque converter lock-up clutch may be felt while driving between 20-45 mph. To minimize the opportunity for the judder to
occur, a software update for the transmission is available. This software update is available free of charge to all affected vehicles regardless of its age
or mileage.*
Warranty Extension: Torque Converter
If the judder returns after the transmission software is updated, the torque converter may need to be replaced. To increase customer confidence,
American Honda is extending the warranty on the torque converter in affected vehicles to 8 years from the original date of purchase or 105,000
miles, whichever comes first.
The warranty extension does not apply to any vehicle that has ever been declared a total loss or sold for salvage by a financial institution or insurer,
or has a branded or similar title under any state's law.
