You said he didn"t change the pilot/bearing and given everything your describing it sounds like thati= is the problem. Most of the trucks I"ve worked on had bearings for the pilot vs a bushing. Given that you said the transmission slid in fairely easily that could easily indicate the bore in the bearing/bushing was worn. With the wear the weight/centrifugal force of the disc acting on the input shaft could be causing it to get cocked in the hole while it"s turning. This, in turn, would tend to keep the shaft turning even when the clutch itself was released. Even if it"s an actual bearing the transmission could still slide in easily like it should but the bearing itself could have a few sticky spots that won"t allow the shaft to turn freely and instead sticks on occasion.
Second idea if the bearing/bushing wasn"t changed there may be trash/gunk/hardened grease built up in the bore of the bearing. Depending on the amount of crud this, again, could be acting on the end of the shaft when the transmission is pulled all the way in and causing it to turn.
If it were me I"d go ahead and pull the transmission back out before spending another minute on it and do what should have been done the first time and change the bearing.
