Problems after dealer work.

Abenitez

Hi guys im a proud owner of a 2009 370z, but with only 19k miles my csc went to crap. so i got it towed to the dealer two weeks ago and finally picked it up today. It took so long because the tail housing was not lining up right and a deformed bushing i think on the driveshaft and differential, but was covered by warranty. Any way after picking it up today i noticed my shifter going to far to the right as if a guide or something is missing i have to wing it going into 5 or 6th gear, It feels like there should be a few more gears past 5th and 6th, what im trying to get at it wasn't like this before should i take it back? Or any advice as in where to look maybe something's loose idk. Any help will be appreciated.
