THE ENGINE RPM RETURNS TO IDLE IF THE DRIVER TAKES THEIR FOOT OFF THE ACCELERATOR PEDAL. THIS CONCERN IS CAUSED BY IMPROPER CALIBRATION OF THE PCM FOR TORQUE TRIM CONTROL. TORQUE TRIM CONTROL IS USED ON THIS M/T TO ADJUST THE ENGINE RPM TO A SUITABLE SPEED FOR THE GEAR AFTER SHIFTING. THE FUNCTION ONLY WORKS WHEN THE DRIVER STEPS ON THE ACCELERATOR PEDAL WHILE SHIFTING TO HELP ACHIEVE SMOOTH SHIFTS. TO CORRECT THE PROBLEM, THE PCM SOFTWARE HAS BEEN MODIFIED.","document":null,"url":"https://open.wenmarpro.com/bulletins/10097401","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"},{"id":"transmission-control-module","name":"Transmission control module","parent":"powertrain"}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"MAZDA3","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_mazda_mazda3","2013_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
