Muncie 4 spd. not staying in 4th.

Quick question guys, my 1970 m-21 muncie does not want to stay in 4th gear, wants to pop out of gear under even light throttle, the trans is rebuilt ,clutch,throwout bearing, roller pilot bearing are all new. Shifts up & down fine in all gears & all linkage moves freely & goes in fine while running through the gears on the hoist,& no odd noises any thoughts on what to check out?
Thanks Gary
