I love my 6 spd but with the 6 spd you will need to be alittle more aggressive when shifting. And I have noticed on my 04 sometimes it feels like it double clicks going into 1st gear, if it is not all they way in it will pop out, and will scare the sh it out of you when it happens the first time.
Did it to me a couple years ago and I know exactly where I was at and everything that happened.
But shifting alittle more aggressive and have not had another problem
