Hey guys might be a bit of a noob question buut the other day I was driving and managed to here a grinding noise when shifting from 2nd to 3rd. I think it was because I wasnt concentrating and the clutch was not all the way depressed. It was around 3500RPM and lasted about 1 second

Have I caused any damage to the box or syncros by doing so. Is it worth changing the tranny oil or?

Never have done this before so I am not quite sure.

I probably do that a couple of times a year due to brain fade. Its only worth changing the oil if its due for a change, or if you don't know when its due for a change, so you do one as a precaution then get back to the normal drain interval.

Will be fine mate. Too much of it will wear out your synchros though. That sound you heard was the dog teeth grinding against each other because you hadn't clutched in properly. Unless your synchros start making noise regularly on gear changes you have nothing to worry about.

Ye temporary brain fade...

I didn't slam it in, as soon as it grinded I am pretty sure it went back into neutral and then I put it into 3rd again.

Reason I asked was I thought there might be some metal shavings in the oil and well its never happened before so I didnt know what damage I had caused.

if there was and metal shavings, it would be bugger all, especially when you remember that there is a few litres of oil in the gearbox. secondly, i'm pretty sure the drain bolt has a magnet in it to collect any metal shavings to stop them doing any damage.

cleaning the teeth grinding - take foot off clutch a little too early and hear the clutch teeth give a squeel.

hard grinding - crunching sound..

Well It wasnt like a crunch squeel more like a grinding i guess. I cant describe it really.

It is identical the sound first sound at 1.32 of this video.

    • Ha ha ha, that's fair mate! We have the crackhead dogs now. Mainly because the missus wants the crazy dogs while she still has the energy and capacity to be able to keep up with them! Ha ha our current two are both Working GSD, there brothers and sisters (from the same litters) are in Police, Corrective Services, and I believe one did end up in defence force too. They're wild and fun, yet right now, both curled up asleep on the lounge room floor while we watch some TV. Mal is very likely the next dog (unless I get my couch potato guardian dog 😛 )   What are your Kitties names? Are you planning some house work, like those high kitty shelves, built in scratching post, and some cat passages from one room to another room?
    • Maine Coone, did look at but to big and fluffy As for performance dogs, we had Mals at work, performance dogs are fun to watch, but, way to much work for this old rooster
    • Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.
    • You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛
    • Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.
