This may be caused by the torque converter one way clutch. To correct the condition, perform the torque converter stall speed test. Refer to Workshop Manual (WSM) Section 307-01B > Special Testing Procedures > Stall Speed Test. For this specific condition, the line pressure test is not required prior to performing the stall speed test. If engine stall speed does not reach the minimum RPM range specified, replace the torque converter, torque convertor hub seal, and fluid filter. Perform the transmission fluid cooler backflushing and cleaning procedure and refill the fluid. Refer to WSM, Section 307-01B.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10198602-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10198602-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10198602","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":["P054F"],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_ford_f-550"]},{"make":"FORD","model":"F-650 SD","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_ford_f-650"]},{"make":"FORD","model":"F-750 SD","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_ford_f-750"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
