Default acidental grinding on 5 speed

There are a few times I don't depress the clutch pedal enough when I shift and I get the occasional grind I only have about 10000 miles on my xB. Based on your experiences am I facing a potential problem in the future? I think the clutch is fine ...sometimes my foot doesn't puch in the pedal enough I think. I never jammed it in gear...I back off when I hear the grind

In total since owning the car I experienced it four times.

You should be OK. Just don't make a habit of it.
Maybe move your seat up a notch so it will be easier to fully depress the clutch pedal.

Hmmm I have had some of this grinding myself, mine is an 06 xB. I only have 1500 miles on my xB. I have a tendency to grind upshifting into 3rd gear. The shifter seems a bit notchy to me on this shift. When my right hand doesn't get to the right spot in time my foot moves off the clutch and "grind". I don't always feel this notchy feeling when moving from second to third but often enuf to be concerned about it. Anyone else had shifter difficulties besides us 2?? I have been considering a dealer trip for this issue, maybe something is amiss?? My worn out sloppyass junk 1972 Nissan shifts more consistantly from second to third.

^^ hehe, yea, my "mindless" grinds happen in third gear as well. Happened in my "slump" when my shifting wasn't too great. I got too fast with my clutch movement on the 2-3 shift and would clutch out too early.

It's not that big of a deal if you're only doing it a few times. Something like a few times a year should be avoided, but isn't going to make your tranny quit at 10,000 miles. There are plenty of people who grind maybe once a month or every few months. Just don't make a habit of it and chastise yourself when you do so (although that noise should take care of that)!

Now if you're grinding everyday, then you need to reevaluate your shifting. Go slow on all your shifts, and think them through. Eventually you should get better. Slow shifts are better than grinding your gears to metal flakes.

If your shifter feel is too "notchy," those are the synchros. If you're unhappy with them, you can try a gear oil change to a quality synthetic gear oil, like Redline (MT-90 I believe). Many who have done this report better shifter feel, because it allows the synchros to work better and faster (won't feel so "notchy").

Default grin - ding!

Not to worry it happend to plenty of people. It happened to me about three time since ownership. twice from 1st to 2nd because i was driving lazy "fast foot/slow hand" and once from 2nd to 3rd "no excuse for that one" I have 15k on my tc.

I don't know. It's weird. I've done it twice in the same week, this past week. I was mistimed, obviously, but still... I think it happens more when the gear oil is still cold and the synchros don't engage as quickly as your leg is trained to think it does. This has never happened with this frequency to me before.

Before you are able to control your limb movement, you're already clutching out... and...

Today I ground it 3 times going to third I wasn't shifting fast or anything. It simply hits the 3rd gear spot feels right, like it is fully engaged, but it isn't...very annoying.

Either my shifter is crappy of the synchos don't fully throw sometimes. When mine does it it will tend to do it a few times in a short period of time (even tho I am trying to make sure it doesn't) and then it won't happen again for a week maybe, but when it has done it once it has seemed to do it a couple or more times in an hour of driving. SO, either it is touchy or it isn't but it seems to decide which:/

yea. I'm thinking maybe a gear oil upgrade/change (to Redline synthetic) might be in order, but I kept telling myself I'd wait until 10k so I wouldn't "waste" the oil that was, after all, included in the $19,000 for the car.

Who knows. I guess I'll just try to go a little slower.

Sounds like 2 gears grinding together, the sound of a moving gear hitting and trying to engage a stopped gear, sounds kinda like and airhammer running against a good size piece of 1/4 plate steel. BRRRRRRRRRRRRRRRT!!!

Like terrible ted said. Basically, its a sound that makes you want to punch babies in the face

In your case it sounded like you just popped out of gear. It's happened to me before as well when I got too excited and didn't move the stick all the way in gear... not a big deal when that happens, though

Oh no!! Not the sound that makes me punch infants!!! NOOOooooooooooo.......!!!!

Dane cook is the man!


I've done the whole grinding thing before. Like everyone else has said, I dont believe it is a big deal as long as you dont make a habit out of it, and you stop as soon as you hear the noise!
