transmission whistle

When I let off the gas at hwy speed i get a whistle from the tranny , is this normal?

 

I have a funny noise that only happens in 2nd gear when accelerating.

 

OMG, mine has always done this too. Do you have the 6 speed?

 

yes I do

My daughter took the truck the other day and when she got back told me the truck made a weird noise so we went for a ride and when I let off the gas it made that whistle noise and she said that's the noise she was hearing,I'm so use to it now I don't notice it anymore but I'm just wondering if it's normal?

 

I'm not sure if it's normal or not. Mine's been doing it for a couple years but hasn't gotten any worse. I guess it's a good sign that we're both experiencing the same thing

Mine also makes what seems to be the same noise at a lower pitch while in 4th gear around 40mph with light pressure on the gas. I took it to the dealer once, and they looked it over and couldn't find anything wrong. Their determination was that it's a "normal gear noise".
