Hi Moe, if your hearing a whinning sound (somewhat like a low power steering fluid sound) only in gear, reverse or drive, dissapating as vehicle speed increases but may reappear at shift points, it may very well be the torque converter, inside there is a torrington bearing that wears and will cause that noise during stall conditions, if so, the torque converter would need to be rebuilt or replaced, good luck.

Kevin.

Same exact thing happened to me once, it turned out to be the stator shaft splines. They were completely worn off. The car will run pretty much normally, but the supercharger whine sound will be there when stopped, dissipates once you get rolling.

The stock stator shaft was not case-hardened, but the aftermarket part is. Those splines are responsible for holding the center pump drive in the torque converter as I understood it.

Continue driving it, and you will only add more trash to the system.
