IF you think what ATF does, it lubricates gears and bearings, but is also formulated to work with clutch packs etc. There's no reason why it won't work to do a good job of lubricating the gears and bearings in a manual box, the only issue being if it will work with the synchro rings properly. Some synchro rings are designed to work with ATF. I woudn't use it in a box where it isn't specified.
