A903 issues

Hey guys, thought id give my luck here in the trans department. So ive got a 72 dart swinger (/6 with 3 on tree) but i have 2 issues with it.

1: when in neutral and foot off the clutch, i hear a whirling sound. It goes away when i press in the clutch.

2: when it was cold, it would bind going from 1st to 2nd unless i double clutched. When i had it in a shop to fix a fuel leak (they fucked things up), i told them to grease the linkages while they had it. Well i pick it up, and one of the issues with it now is that it pops out of 2nd now. At 1st it was just falling out if i didnt release the clutch soon enough. Now it pops out the moment i start to release the clutch. The shop is claiming bad synchros, but it didnt do this before i left it with them and started within an hour of picking it up.

Thoughts?
