Old design originally required a coolant line running to the top of the bell housing, the new design has omitted the hole and need for the coolant line. The new/superseded design can be used in place of the old/original design, and the coolant hose with fitting is no longer needed.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019159-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019159-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11019159","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-70","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_mazda_cx-70"]},{"make":"MAZDA","model":"CX-70 PLUG-IN HYBRID","year_from":2025,"year_to":2025,"match":"base","vehicle_ids":["2025_mazda_cx-70"]},{"make":"MAZDA","model":"CX-90 PLUG-IN HYBRID","year_from":2024,"year_to":2025,"match":"base","vehicle_ids":["2024_mazda_cx-90","2025_mazda_cx-90"]},{"make":"MAZDA","model":"redundant CX-90 HYBRID","year_from":2024,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
