TSB 21-2059

Some 2020 Mustang GT500 vehicles may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P175E and/or P0874 set in the transmission control module (TCM). This may be due to the transmission fluid pressure sensor parameters set in the TCM. To correct the condition, follow the Service Procedure steps to check the transmission fluid pressure sensor and reprogram the TCM.
