# Service bulletin B16\-063

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin

- Published by NHTSA: 2018\-04\-16

- NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER

## NHTSA's summary

Service bulletin \- After the software update, some vehicles based on how they are driven \(extreme conditions\) may still experience ATF deterioration after updating the PGM\-FI or A/T system and the shudder may return. The problem is typically diagnosed as a bad torque converter \(TC\). There is no damage to the TC, but because the ATF has deteriorated, it needs to be changed even though the ?ATF Service Due? message has not appeared.

- [B16\-062](/bulletins/10145420.md), 2018-10-15, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER. Service bulletin \- A judder from the torque converter lock\-up clutch may be felt while driving between 20 and 60 mph. 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.

Service bulletin \- The MIL comes on with DTC P0430 \(front bank catalyst system efficiency below threshold \[Bank 2\]\). The PCM software may misinterpret sensor inputs as a deteriorated catalytic converter.
- [Service Bulletin](/bulletins/10108863.md), 2017-07-31, Service bulletin: EQUIPMENT:APPLIANCE:AIR CONDITIONER; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Service bulletin \- The MIL comes on with DTC P0134 \(rear A/F sensor \[bank 1, sensor 1\] heater system malfunction\) and/or P0154 \(front A/F sensor \[bank 2, sensor 1\] heater system malfunction\). The PCM misinterprets the heater system input from the A/F sensor and sets DTC codes P0134 and/or P0154.

"SERVICE BULLETIN \- AFTER THE SOFTWARE UPDATE, SOME VEHICLES BASED ON HOW THEY ARE DRIVEN \(EXTREME CONDITIONS\) MAY STILL EXPERIENCE ATF DETERIORATION AFTER UPDATING THE PGM\-FI OR A/T SYSTEM AND THE SHUDDER MAY RETURN. THE PROBLEM IS TYPICALLY DIAGNOSED AS A BAD TORQUE CONVERTER \(TC\). THERE IS NO DAMAGE TO THE TC, BUT BECAUSE THE ATF HAS DETERIORATED, IT NEEDS TO BE CHANGED EVEN THOUGH THE “ATF SERVICE DUE” MESSAGE HAS NOT APPEARED. MAKE SURE THE VEHICLE IS UPDATED BY REFERRING TO THE INSPECTION PROCEDURE."

"SERVICE BULLETIN \- A JUDDER FROM THE TORQUE CONVERTER LOCK\-UP CLUTCH MAY BE FELT WHILE DRIVING BETWEEN 20 AND 60 MPH. 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 TRANSMISSION FLUID DETERIORATES QUICKER THAN EXPECTED WHEN IT IS EXPOSED TO INTERMITTENT HIGH HEAT LOADS UNDER SPECIFIC DRIVING CONDITIONS. A SOFTWARE UPDATE IS AVAILABLE TO MAINTAIN THE TRANSMISSION FLUID TEMPERATURE WITHIN THE DESIRABLE RANGE UNDER ALL DRIVING CONDITIONS AND ELIMINATE THE POTENTIAL FOR THIS JUDDER."
