This surging is in the longitudinal direction, felt about 2 cycles per second, and occurs in the locked up 1st gear. This may be caused by the torque fluctuation and the torsional resonance in the torque converter. To correct this concern, the PCM software has been modified to reduce the torque fluctuation.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10176972-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10176972-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10176972","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"MAZDA3","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_mazda_mazda3","2020_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
