NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS/RANGES DESCRIPTION AND POSSIBLE CAUSE

22	Noise occurs at idle when vehicle is stopped in all positions/ranges
DESCRIPTION	Transmission is noisy in all positions and ranges when vehicle is idling.
POSSIBLE CAUSE	High-pitched noise emitted from AT at idle may be caused by pressure control solenoid or oil pump. There may also be engine noise (idle speed mis adjustment and/or V belt noise) NOTE: If a noise is emitted during shifting only, the malfunction is in solenoid. 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 Transmission On-Board Diagnostic and Automatic Transmission Basic Inspection are conducted. (See BASIC INSPECTION .)
