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. - [B16\-046](/bulletins/10145419.md), 2018-10-15, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER.
