Service bulletin B16066

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.

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 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 software is updated by referring to the INSPECTION PROCEDURE.
