First, nice to meet u guys in this club. I've a question about changing the gear oil and differential gear oil? My car is Auto R33 GTST, and i think it is time to change the gear box oil. So i wonder what is the differs between the gear oil and differential gear oil, and which brand oil is good? please advice!

I've heard some people said for all the GTST has got LSD function on it. Is that correct? If it is correct, then how can i know my car has got LSD function?

Cheers:)

Differential oil is normally thicker.... e.g. the stuff I use is Fully Synthetic diff oil 80w(thereabouts maybe 90w?)-140 LSD diff oil GL5

Manual g/box oil is normally 80w-90..... But for you, you need a specific auto tranny oil - not the stuff thats used in manual g/box's

You must use Auto Trans fluid on your gearbox. Not a gear oil. Just get a coupla Castrol Dexron III ATF bottles and use that! Make sure to flush it a few times as you only get about 1/3rd of the fluid out everytime you drain it.

For the diff, any GL5 rated oil would be fine. 75W-90 is ideal.

Yes mate, they do have the ATF synthetic oil as below the web-site.

But i just can't find that kind of the ATF oil in N.Z. Anyway i think i would go for the normal ATF gear oil first. By the way, so if i take my car to the garage to change the gear box oil, and diff oil. Do i need to say to them? I mean is normal when change the gear oil, will they also change the diff oil?

Cheers mate!!

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
