TECHNICAL SERVICE BULLETIN: TCM MIL ON DTC P074100 LOGIC IMPROVEMENT - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides the procedure to improve the logic of the Transmission Control Module (TCM) on some 2020MY Telluride (ON) vehicles, produced from February 6, 2019, through December 9, 2019, which may experience lack of engagement of the torque converter damper clutch with illumination of the MIL and DTC P074100. When this occurs, the vehicle retains motive power, but transmission gear change smoothness can be affected.

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.
