It is possible the vehicle may also have an illuminated malfunction indicator lamp (MIL) or diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to incompatibility of the adaptive calibration to adapt to hardware wear-in over time. To correct the condition, follow the Service Procedure steps to overhaul the main control valve body and/or perform an adaptive learning drive cycle.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201905-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201905-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10201905","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"}],"codes":["P0729","P0731","P0732","P0733","P0734","P0735","P0736","P0751","P0752","P0756","P0757","P0761","P0762","P0766","P0767","P076F","P0771","P0772","P07D9","P07F6","P07F7","P2700","P2701","P2702","P2703","P2704","P2705","P2707","P2708"],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2018,"year_to":2021,"match":"exact","vehicle_ids":["2018_ford_expedition","2019_ford_expedition","2020_ford_expedition","2021_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2017,"year_to":2020,"match":"exact","vehicle_ids":["2017_ford_f-150","2018_ford_f-150","2019_ford_f-150","2020_ford_f-150"]},{"make":"FORD","model":"MUSTANG","year_from":2018,"year_to":2021,"match":"exact","vehicle_ids":["2018_ford_mustang","2019_ford_mustang","2020_ford_mustang","2021_ford_mustang"]},{"make":"FORD","model":"RANGER","year_from":2019,"year_to":2021,"match":"exact","vehicle_ids":["2019_ford_ranger","2020_ford_ranger","2021_ford_ranger"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2018,"year_to":2021,"match":"exact","vehicle_ids":["2018_lincoln_navigator","2019_lincoln_navigator","2020_lincoln_navigator","2021_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
