When I do upshifts from 2-5 or 3-5, when I have 5000-6000 RPM on the tach, I usually get a little bit of a grind, just like I missed a shift. I know I can't be missing that many shifts! if I let the RPMs drop, or never get them up there, there is no problem.

Anyone hear of anything like this or have hints they can pass along.

syncros are going in 5th gear. you must have missed 5th a lot of times, or shift exremely hard into 5th gear

are you stepping the clutch in all the way? try chaning the tranny fluid.. sometimes that helps. make sure you go with nissan mtf or redline

I don't remember missing 5th all that much, if at all.

As to pushing in the clutch, yeah, it's in all the way. I put my foot fairly high up on the pedal. The ball of my foot is at the top of the rubber and my toes on the arm, it's in.

Could a low tranny fluid level do something like that? (and also take syncros / gears with it.)

dirty fluid might do some damage...

low fluid definitely would. low is bad.

a clutch problem? How many miles on your car? Definitely take it to the Nissan dealer to have checked out. Should be covered under 60K mi powertrain wtty.

I assume your under warranty still. Should take it to the dealer but it is always nice to know what is wrong beforehand...

Are you shifting into 5th at a big "angle?" Try making certain that you are pushing into 5th gear by going straight forward.

I was missing third or grinding it doing the same thing.

Doesn't anybody else see the huge gap in syncro speed matching? There's nothing wrong with shifting from 2nd to 5th, but you need to let the RPMs drop a bit. Mechanically the tranny isn't made to be shifted like that. So you have to work with it a bit.

2nd to 5th gear @ 5000-6000RPM's the tranny needs a few seconds to slow down. The input shaft is doing 5000 rpms and the 5th gear syncro is only doing half that at best. Thats quite a load your asking for a syncro which is manufactured to catch/match speeds from coming out of 4th gear. A difference of ~500 or 750 RPM's at best.

Shift it a bit slower, come out of 2nd, wait a second, let your RPM's come down a bit before you put your shifter into 5th. Your tranny will be much happier. Just do the shift slowly and it wount grind.
