it sounds like whining gears and it is only while the truck is in motion. the only time the pitch of the whine can be heard is at low traviling speeds. checked all fluids and there fine. it isn't the supercharger or the motor, it is either the trans, driveline, or something in the wheels, any input is appreaciated

 

the noise only occures in third gear, i put in first second and reverse and there was no whining. and it goes away in overdrive
what in the trany is asscociated with third gear

 

How many miles?

 

46,000 but the fluid is in great shape

 

no one?????
