You probably bought a shitty, used manual transmission that is in need of a rebuild. If you didnt rebuild it, then you should. If the seller said he rebuilt it, he lied.

ya perhaps.....i heard a couple saying it might be a throw out bearing?
the tranny never made that noise before untill a couple weeks after the swap, and sometimes it doesnt make the noise....

I hope you used GL-4 tranny fluid.

You have nuked synchros buddy, that whining sound you are hearing is the synchros winding down from the gear you were just in and the grinding noise you are hearing is the synchros not being able to match up the gears in time before you actually engage the gear. Solution: need to get a new transmission or have the current one rebuilt.
BTW if you drain out your transmission fluid you are likely to see a lot of metal flakes and your fluid will look and smell something like swamp water.
