The symptom can be temporarily repaired by A/T initial learning procedure, but may recur after multiple driving cycles. Applicable situations: *Shifting up: 2-3, (4-5) *Shifting down: 4-3, (6-5) NOTE: (4-5) and (6-5) are felt more than others due to the gear ratio. *Shifting into R: D-R, N-R, P-R Improper control logic of the TCM may cause improper learning of R-3-5 brake engaging speed during certain driving situations. To correct this concern, the control logic of the TCM has been modified.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10210909-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10210909-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10210909","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"MAZDA6","year_from":2017,"year_to":2020,"match":"exact","vehicle_ids":["2017_mazda_mazda6","2018_mazda_mazda6","2019_mazda_mazda6","2020_mazda_mazda6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
