any one have heard of this or had it? some times on a light foot only going up to 2k revs and going to second it has some sort of a whine for jut the second is this normal i only got 26k miles and the truck was never run that hard. A few races here and there but i dont think enough to cause this, i did have the tow haul on a few timesunloaded could that have caused it?
