Car has 82k 3.8
As the car accelerates and slows down i hear the whining noise as it shifts up or down.
No transmissions knocks or problem shifting.. no slips.. runs strong.
Any ideas? or is this just a know issue for the car.

 

The problem is with the underdrive compounder bearings. The bearings were adjusted to tight and cause the bearing to fail and this is causing the whining
