Re: 09 Yukon hybrid noise
If the noise is coming from the Aux pump itself, maybe the pump motor is going bad, or could it be it is not picking up oil? When was the last time you replaced the transmission oil filters? There are 2 filters inside the transmission oil pan and one of them is for the oil being pumped by the Aux fluid pump.
