- [Technical Resear](/bulletins/10211540.md), 2022-05-09, Service bulletin: POWER TRAIN; BACK OVER PREVENTION. American Honda \(AHM\) is investigating certain 2014\-2016 MDXs with a client complaint of front bearing noise coming from the front while driving. The noise can be described as howling or moaning. To fully understand the cause of this condition, AHM would like to collect specific parts from the vehicle prior to you attempting a repair of any kind.

- [BTS\-151101 V2](/bulletins/10193296.md), 2021-05-14, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Replacement TCMs don’t come with trim data. After installation, you need to run a teach\-in \(hydraulic pressure characteristic calibration\) procedure with the HDS. The problem is that A/T DTC P287C \(transmission adaptive values not learned\) is set, which prevents teach\-in. This happens because the TCM is programmed to look for trim data any time the ignition is cycled. If the TCM doesn’t see that trim data, it sets A/T DTC P287C. If any DTCs are set, the TCM won’t initiate teach\-in and, as a result, can’t learn the trim data. It’s a classic catch\-22 situation.
- [SB\-16\-012](/bulletins/10193236.md), 2021-05-13, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. BACKGROUND American Honda has made several shift quality improvements in the 2015 and 2016 TLX V6. SYMPTOM There is a sensation of acceleration while coasting down a hill. There is a sensation of a surge while braking. The transmission feels like it stays in gear too long. CORRECTIVE ACTION Update the TCM software. Clear all DTC’s created during the update and do the idle learn procedure. This software update will change the way the transmission shifts. After the update it may take up to 30 miles for the transmission to adapt to the client’s driving habits.

- [ONLJ8F11022020](/bulletins/10182478.md), 2020-11-11, Service bulletin: POWER TRAIN. Owner Notification Letter \- When the powertrain control module \(PCM\) detects a malfunction in one of the odd number transmission gears, it will set one of four diagnostic trouble codes \(DTCs\). Due to inappropriate calibration of the PCM, the On Board Diagnostic \(OBD\) system cannot properly clear the transmission permanent DTC as required.
