My car wont move in drive
A lot of things can make a that kind of sound and none of then are good when it comes to a rig not moving, I am going to go out on a limb here and say most likely the tranny went bye bye, The sound could be most anything from the torque converter splines to internal sun gears grinding up. I do believe that you will wind up replacing or putting in a rebuilt tranny. HTH
