    Not sure if this sound is normal or not. I can only hear it from underneath the truck.

    If it's a very noticeable " loud" whine , then that's the pump going bad

    Low transmission fluid level or extremely dirty fluid will cause that sound . You should be noticing this sound as the transmission shifts thru the gears

    The trucks got a noisy ping when accelerating. Could that cause the sound of this knock?
