Default A question about gear meshing

I am running 64p on my Pro4 100spur/26pinion. Now, I adjust the mesh according to what has been sited many times (paper in between the teeth, not too tight, not too loose). My problem is the sound....sounds like I am running 48p. I call it the "dirty whir".....after you run a truck in the dirt, it has the light grinding sound. Initially, I though it was the diffs and/or the tranny. Without the motor set in the motor mound, tranny is smooth as butter. Any suggestions? I like my electric to be quiet...not with the "dirty whir".
