Ditto....I can usually tell, but sometimes I find myself downshifting in traffic, then have to accelerate back and I'll forget if I'm in 4th or 5th, etc. I can tell the first few gears apart because they're so spread out, but when they get tight and I have to do the up-down-up-down thing.....I'll admit I lose count! If I'm at a good cruising rpm I don't mess with it, but if I'm at a bit higher speed and not sure if I'm in top, I just pull the clutch and gave her a kick. But I can usually tell 6th apart, because my trans whines like a **** in 6th gear, can hear it over the exhaust and all if you pay attention.

I think 4 and 5 are the gears I really get mixed up.

 

I usually can tell which gear I'm in at the lower end... but atleast that thing would stop me from trying to find 7'th gear... :-)

Dunno if it's worth that much money thoo...
