I'm planning on using Motul Gear 300 in my gearbox and diff when I get the time to do it.

My gearbox was rebuilt 3 years ago because of a 4th gear sincro problem would grind at anything over 4000rpm. Im having problems again but only if shifting quickly at redline. What oil should I use?

You ask like I'm an expert! :P

I have good advice that shockproof will solve your grinding problems, but there's more realisation these days that while it works great in the short term you may be shortening your box's life by using it.

Not sure if any additives like the nulon G70? will help shift quality. Otherwise just go for shockproof and when the box blows up get a new one :D

it's been a week now since i put in redline lightweight shockproof. It shows only slight improvement on my crunching problem from 1st to 2nd. i am wondering how long does it takes to show the full result. Does anyone knows?

Does R33 gearbox crunch from 1st to 2nd on a cold start normal?

Giveitall ... thats impossible to answer ... its not like an antibiotic! or Rehab... It deppends on the actual damage caused in the first place as to whether any improvment will be made....

I use it in mine and it only made small differences to my driving shifting! ITS just that i know its good protection for my fresh box ! Not a tolerence corrector

Well I'm going to use Redline MT90 (it's a 75W/90) oil without the shockproof particles.

I'll see how it goes.

You know a lot of these shift problems could be due to the clutch not fully disengaging, particularly if you have a heavier pressure plate and haven't tweaked the clutch play.

Something to look into before the oil if you are having shift problems. You need virtually the entire clutch master cylinder length used fully to change gears in an R33 with a heavier pressure plate. And it only takes 10 minutes to adjust. :P

Well im scratching my head now thinking what gearbox oil I should use. GTS4 r32 gearbox. Has some noise coming from it when driving, but I was told when I bought the car, that it had an aftermarket gearset in it as well. So not quite sure whether to use redline or not. Main issue is it crunches on a quick change from 4th to 5th.

My gear box crunch when im changing from 4th to 5th (in high rev mostly)and 5th to 4th (in high rev mostly,sometimes low revs), wil it be cuz my clutch is worn? or not disengaging properly? how would i check it?

Edit- at the moment im learning double clutching, which resolve the crunching problem, and it make feels good too.

By the way, I changed my gear box oil to Redline MT90 two days ago, now the crunching problem seems to be gone :blink: ( Iwas using Penzoil or Penrite with Nulon N70 addictive) Cheers

My 2c,

I use MT90 on the boxes that still work fine, and lightweight shockproof on the ones that dont feel so good. Seems to work ok, Ive had MT90 in my R33 GTS-T box now for over 100 000km's still runs 100% pefect with serious abuse.

Thats good to hear, only thing that stoped me using Redline ightweight shockproof is most ppl who has used it have 50/50 opinion. maybe ill use it when my gear box is very bad i guess.

    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.

    • Definitely a hearty eater when we go out, I consider these meals my cheat day as I've been watching my calories in and calories out pretty hard since my little fun size stroke, I've gone from a fat boy of 89 Kg, I'm only 165cm tall/short, down to a almost semi lean 73 Kg over the last few years, I'm currently around 17% body fat which my doctor is very happy with, but, my goal is to slowly get down to and maintain 15%,so yeah, I want all of the protein, carbs, fats and sugars when I go out for a binge
    • There was a great one on Victoria Rd in Gladesville too back in the day. I can only assume GTSBoy is thinking of the mill up on the wollondilly, no restaurant there any more but they have restored the original steam engine on site and run it every few months, have an annual steampunk festival etc @The Bogan, you came to the wrong town for restaurants. we have a few reasonable asian and indian options but the Paragon is as good as it gets otherwise. That brewery is apparently just opened, been meaning to give it a go some time. The Highlands have plenty of fancy options but I suspect you are more a hearty eater than fancy eater
