If the fluids mix, the engine and transmission may be permanently damaged and require replacement. These vehicles previously had the transmission replaced because the transmission warmers leaked. In rare cases, these vehicles may have also overheated but because the issue was under investigation, a standard repair procedure hadn't been developed. Further action is needed before the vehicle is completely repaired.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10166511-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10166511-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10166511","components":[{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ACURA","model":"MDX","year_from":2016,"year_to":2017,"match":"exact","vehicle_ids":["2016_acura_mdx","2017_acura_mdx"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
