I meant: there should hardly be any end play of the input shaft--I would think .005 or so. That would be the play of the balls in the races. The snap rings should not allow any movement of the bearing in the case or the shaft in the bearing.

The mainshaft assy complete should have about the same end play as that is controlled by the bearing at the rear of the case and a similar arrangement of snap rings.

On the mainshaft itself, there should be no perceptible movement of the gears axially if it has been rebuilt correctly as those bearings should all be preloaded by the rolled-on ring right after the spine that the synchro assy slides on.

Which end play did the shop reduce to 1/32? I don't get that one.

Running in overdrive or out should not make a scintilla of difference.
