Original wording in English

"Flash: Transmission Control Module (TCM) Updates Customers must experience a Malfunction Indicator Lamp (MIL) illumination and the vehicle must exhibit/set the following Diagnostic Trouble Code (DTC): ● **P0731 - Gear 1 Shift Incorrect Ratio.** The customer may describe the following: ● **Severe bump or clunk during high engine rpm and low vehicle speed 1-2 upshift.** ● Unable to set desired gear manually from the steering wheel controls This bulletin involves reprogramming the TCM with the latest available software."

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
