Official summary
Service Bulletin - The shift position indicator ("D" light) starts flashing due to DTC P2817, (Shift solenoid valve O/P [pressure control solenoid H] stuck off) being set. When the TCM checks the drive pulley oil pressure, it misreads the pressure as high even though oil pressure is within specification.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
