Hi!...

It's a good question...(and I will do my best to give you the least technical explanation I can, which should be easy!..LOL!)

..and I reckon is one that is commonly asked, or at least considered.

But I can only be very general in my response, as each driver and gearbox performs/wears differently.

In my own personal experience..... Nissan boxes are noisy!...Simple!...

Don't get me wrong..I love them,..they are strong and take a lot of abuse...(we all know that!)

Synchros do wear, it seems that 2nd and 3rd are the first to 'slow down'...

Thrust bearings are notorious noise makers....on our cars...(I just got a new Rissan one installed, with only a slight decrease in noise).

Sometimes the use of specialised additives..in your gbox can help, sometimes they don't, sometimes they can hurt your box.

Where is your 'crunch', ....when does it occur.....does it occur when the box is cold......in hot/cold weather....does it occur during 'spirited' driving?....sometimes oil viscosity/quality can make all the difference.

It may be that you need to look into (major) servicing of the box.....it could be a few dollars?..could save you a few too!

I have always let my cars warm up....engine and box, prior to stabbing...could it make a difference to you?...dunno.

Will an additive (<>60-120 buh) help you??.......dunno...could be a could place to start, for cheap.

Synchro/box service??......yep, that should do it!......but........$$

I will let the experts give you the tech run down.....but just letting you know that many of us experience "the crunch", in one form or another........they are a noisy/crunchy box nowadays!!

Cheers.

Your synchronising gears are worn.......or your clutch is stuffffffffffed!

I think a few memebers here have answered that already for you.

Where abouts in Melb are you?.....

there is no load on your gbox when stationay as its not engaged so its technically doing f-all thats why its smooth.

I have the same problem, second and third crunch bad, But only when cold, after driving to work leaving it all day and driving home its fine, all my gears are smooth. I was hoping it would only be the gearbox oil or something cheap haha.

seems that in YOUR case....an additive or oil flush and application of a quality oil MAY help you out.

Check it and come back to us.

$$$$$$$$!!!!.........is it just a 'heavy duty' clutch...or one of those craaaaazzzeeee puck/button clutches...(can't stand those things on a road car).

Did you put it in YOself?...Is there a chance of going back to the person who charged you (that did the work)?????

A clutch and a synchro set are very different things.....

A heavy duty Clutch could be making the problem worse...I just don't know!

We'll wait to see what the rest of the guys suggest.......just hang on.

nah i bought the car like that o_O"
