BACKGROUND
American Honda is extending the warranty on the 9-speed transmission warmers to 10 years from the original date of
purchase with unlimited mileage.
This warranty covers vehicles where the engine coolant and ATF mix because of an internal leak in the 9-speed
transmission warmer.
No fluid will be visible outside of the warmer.
If the transmission warmer leaks, it may cause one or more of the following symptoms:
• The vehicle overheats
• The transmission shifts poorly
• The transmission chirps during 3-4 shift
This bulletin only applies to vehicles where the client came in with at least one of the listed complaints and the
warmer fails the pressure test.
Transmission warmers may be called in for inspection and if they are found to be not leaking, your claim will be
subject to debit.
This warranty extension will 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.
CLIENT NOTIFICATION
Owners of affected vehicles will be sent a notification of this warranty extension.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.
CLIENT INFORMATION: The information in this bulletin is intended for use only by skilled technicians who have the proper tools, equipment,
and training to correctly and safely maintain your vehicle. These procedures should not be attempted by “do-it-yourselfers,” and you should not
assume this bulletin applies to your vehicle, or that your vehicle has the condition described. To determine whether this information applies,
contact an authorized Acura automobile dealer.
