I recently had my gearbox oil changed and to make sure I got some quality oil I went and purchased Syntrax 75-90w ($80 at trade price) with a teflon gear treatment ($15)

My problems started shortly after........

I noticed my 2nd gear started to crunch shifting either from 1st to 2nd or down from 3rd back into 2nd at 3000rpm+

Now ordinarily I would guess that the syncro is dead but the crunching only occurs after about 30 minutes of driving which indicates that the oil temp in the gearbox has something to do with my problem. To make things extra complicated the crunch into 2nd only occurs when I change over 3000rpm.

At the moment I take off in 1st....put the clutch in... wait for rpm to drop to 2000rpm and gently put it into gear... VERY annoying!

What do you think? Selector, synco????

Other than the crunch in 2nd the car is driving beautifully with no performance issues once the 2nd gear has been selected..

Ill tell you whats wrong...It says Nissan on the container, and it doesnt look racey:)

I tried Castrol, Redline and Fuchs...the fact that they all feel as good as one another hopefully means my box is in ok nic...probably should stick with the one oil though????

If you are doing say 500kms track work per approx 6,000-8,000road kms...how often shoudl you be changing the gearbox fluid?

      Shoota's R33 GT-R RB30/26

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!

      Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
