You know how I roll lol.

 

So I have some gear whine...

MOTHER ******* **** *** BITCH MONKEY ******* TURD SNIFFING *****!

Okay.....now that that's out of the way, I'm getting a little gear whine around 50-55mph, but that's the only time I can hear it. I didn't put any friction modifier in when I put the fluid in, if I add that will it go away? Or no...

 

The diff is supposed to have FM in it... better add some.

 

My friends 99 GT had gear whine at those speeds.. It was a very deep whine too. It never did go out the time he had it.
