20 | Noise occurs at idle when vehicle is stopped in all positions/ranges
DESCRIPTION | • Transaxle noisy in all positions and ranges when vehicle idling.
POSSIBLE CAUSE | • Malfunction is in pressure solenoid or oil pump which causes a high-pitched noise to be emitted from transaxle at idle. Note • If a noise is emitted during shifting only, malfunction is in shift solenoid A, B, or C. • If a noise is emitted during shifting at certain gears only or during deceleration only, it is gear noise. • Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.
