Uh oh synchros............. I think your first gear synchro might be shot! Sooooo I'd definitly talk to the dealer and if its covered under warranty then do it....... but DO NOT sign off on anything until its forsure that its covered. If not take your work else were cause the stealership will charge you 3hrs to take the tranny out, then whatever it is to rebuild it (All Data tells me 10hrs for rebuild) then 3hrs to put it back in...... In reality any tranny shop can have that tranny out and back in, in about 3hrs, trust me I know ;)
Best case scenario is the shifter linkage which isnt bad to replace :)
