Symptom Troubleshooting - Automatic Transaxle [AY6A-EL]: NVH Mazda 6 GJ

NO.20 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS [AY6A-EL]

20Noise occurs at idle when vehicle is stopped in all positions
DESCRIPTIONTransaxle is noisy in all positions when the vehicle is idling.
POSSIBLE CAUSEThe malfunction is in the pressure solenoid or oil pump which causes a high-pitched noise to be emitted from the transaxle at idle. NOTE: If a noise is emitted during shifting only, the malfunction is in the C1 clutch, C2 clutch, C3 clutch or B1 brake. If a noise is emitted during shifting at certain gears only or during deceleration only, it is gear noise. Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION [AY6A-EL] .)
