REVISION SUMMARY
• 2017 Pilot was added to AFFECTED VEHICLES.
• Two hoses were added to PARTS INFORMATION.
• Information was added to WARRANTY CLAIM INFORMATION.
BACKGROUND
Some 9-speed transmission warmers were improperly manufactured and allow the engine coolant and ATF to mix. If the
fluids mix, the engine and transmission may be permanently damaged and require replacement. These vehicles
previously had the transmission replaced because the transmission warmers leaked. In rare cases, these vehicles may
have also overheated but because the issue was under investigation, a standard repair procedure hadn’t been
developed. Further action is needed before the vehicle is completely repaired.
Make sure you review this bulletin in its entirety before starting. There are multiple repairs available, and the correct one
for the vehicle you are working on is based on your inspection and customer interview responses.
CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.
Some vehicles affected by this campaign may be in your new or used vehicle inventory. Repair these vehicles before
they are sold.

CUSTOMER 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 Honda automobile dealer.

SERVICE ADVISOR
Ask the customer if the vehicle overheated, for example, if the MID showed a message Stop Driving Engine
Temperature Too Hot or there was steam from under the hood. Other signs include coolant leaking from the radiator
cap or the coolant reserve tank.

The vehicles in this campaign had the transmission previously replaced. The vehicle may have overheated due to the
warmer leaking on the previous repair; ask the customer if the vehicle overheated before the transmission was
replaced. This will help your technician decide what repair needs to be done.
Write down the customer responses on the RO.
NOTE: Any engine replaced without this documentation on the signed RO will be subject to debit.

CORRECTIVE ACTION
Inspect the warmer, and based on your inspection and interview with the customer, do one of the following:
• Replace the transmission warmer, replace the radiator, coolant hoses, thermostat, coolant reserve tank,
2 ECT sensor (1 and 2) O-rings, and flush the cooling system.
• Replace the transmission, radiator, coolant hoses, thermostat, coolant reserve tank, 2 ECT sensor (1 and 2)
O-rings, and flush the cooling system.
• Replace the short block, cylinder heads, radiator, thermostat, coolant reserve tank, all of the coolant hoses, 2 ECT
sensor (1 and 2) O-rings, water passage, water connecting pipe, and flush the heater core.
• Replace the radiator, coolant hoses, thermostat, coolant reserve tank, 2 ECT sensor (1 and 2) O-rings, and flush
the cooling system.
• Replace the short block, cylinder heads, transmission, radiator, thermostat, coolant reserve tank, all of the coolant
hoses, 2 ECT sensor (1 and 2) O-rings, water passage, water connecting pipe, and flush the heater core.
