Downshifting may continue, when safe entry conditions are met for each gear, and the IPC display will show the available gears counting down one by one as the vehicles' speed and engine rpm decreases. This may be due to a chafed wire harness in the SelectShift® +/- circuit. To correct the condition, follow the Service Procedure to repair the circuit.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11006771-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11006771-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11006771","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-150","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150","2024_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
