The SAT feature is intended to provide common performance for an empty vehicle as would be expected for a fully loaded vehicle. The feature restricts the acceleration capability for empty vehicles where drivers utilize significant accelerator pedal input. When the SAT feature is non-functional, drivers who reach elevated torque/acceleration rates will not see the desired torque de-rate that the feature is expected to deliver.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201641-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201641-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10201641","components":[{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"},{"id":"torque-converter","name":"Torque converter","parent":"powertrain"}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"TRANSIT","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_ford_transit","2021_ford_transit"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
