My Honda Accord 2004 is making a whining sound when I start it up. It fades while driving buy it comes back every time the car accelerates from 1st to 2nd. It is an automatic but it is about that time frame that the sound occurs.
I’ve checked most things but am no expert. Transmission fluid, power steering, antifreeze, battery are all topped off and I just had an oil change (where I did use regular vs. synthetic which might be a factor but I don’t know).
I also recently had the serpentine belt fixed but it sounds like the noise is coming from that area when the hood is up.
Can someone help with advice.
