CONDITION SUMMARY:
Situation: A 'howl' noise may be evident from the vehicle at low­speed overrun (between 1,800­1,100 RPM).
Cause: This may be caused by the automatic transmission oil cooler transmitting an oil flow noise through the front
subframe which causes excessive Noise, Vibration and Harshness (NVH) into the cabin area.
Action: Should a customer express this concern, follow the Service Instruction below.
