370Z 6speed manual shifting problems
 

I have a 370Z with a 6 speed manual gearbox. It works fine except going from 1st to 2nd there can be a bump and grind. Not every time but more often than not it will make a clunking sound if I pull straight down on the shifter. I can shift from 1st to the neutral position hesitate a bit then down into 2nd without any grind or clunk. Has anyone experienced similar problems?

Try changing the fluid to a really good synthetic. I know mine shifted smoother when I did.

Dude dont force the gears in give the synchro some time to align ur running a shitty tranny fluid you have to use the good stuff.
