I had a 5 speed.
Box was stupid. Literally, it would hold gear for no reason, there was a blank spot taking off from a stand still, revs were high and she chewed fuel, wouldn't kick back a gear when I wanted too and would when I didn't.
End of the day I bought it with 32, 000 odd k's and sold it at 35, 000 odd k's.
Uber sh*t gbox dont do it. 6 speed boxes feel so much more smoother and responsive.
