This test utilizes the pressure and vacuum transducer (PVT) when available. Workshop Manual (WSM) updates related to this diagnostic procedure are planned for release in Q4 2026. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification for transmission replacement.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11033775-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11033775-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11033775","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2021,"year_to":2026,"match":"exact","vehicle_ids":["2021_ford_bronco","2022_ford_bronco","2023_ford_bronco","2024_ford_bronco","2025_ford_bronco","2026_ford_bronco"]},{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2026,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer","2023_ford_explorer","2024_ford_explorer","2025_ford_explorer","2026_ford_explorer"]},{"make":"FORD","model":"RANGER","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_ford_ranger","2025_ford_ranger","2026_ford_ranger"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2026,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator","2022_lincoln_aviator","2023_lincoln_aviator","2024_lincoln_aviator","2025_lincoln_aviator","2026_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
