Service bulletin LTB01289NAS1

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.

Upon further diagnosis, DTC (Diagnostic Trouble Code) P07D4-07 and/or P07DF-07 may be stored in the Transmission Control Module (TCM).
