One trick to aid grinding synchros, which we have had quite a bit of success with, is to use a 50/50 mix of gear lube and ATF. The ATF has plenty of lube, but also has a butt load of detergents which really clean the synchros up and usually gets them working again. This might be worth a shot before seeking a new tranny...

ATF is way thinner, that doesn't seem like such a good idea. Redline MT-90 or MTL would probably be a better way to go. I use MT-90 and it's been good to me.
