sounds like syncreos in the trans. It means a rebuild is in order. If the clutch was the problem it would likely be in all gears. most trans have this problem when the syncroes go. Here i rebuilt a trans for a guy with a mk3 turbo and it cost around 800.00 plus labour. If your mechanically inclined and use the tsrm found on here you can do it yourself. Just need some time and patience and keep everything clean! Hope this helps.
