I feel worser with redline oil? why?

[ken]

Just put the lightweight shockproof redline oil into my gearbox today. Now I can easily change to 2nd gear when the car is cold. But, I feel crunches for 1st, 2nd and 3rd gear, even when the car is warm. I think that it's worser than before. The crunches is absolutly noticeable.

The old oil that drain out from the gearbox is something like auto transmission oil.

What happen to my gearbox that react with the redline oil like this? any ideas?

:shake:

Sorry, no idea, my box improved 1000% with redline, crunches gone. Perhaps its time to see a gearbox specialist.

Give it an easy 1000km+ before you make up your final decision on the Redline Oil.

For the first few days I was like "mannn i paid $100 for this stuff".... but now 5000+ km on and its the best $100 I've spent on my car.

How Much oil did you put into the box?

The hand book that came out with my car say's 2.8L but I have since found it's more like 3.6L that should go into the gear box on a r33 Manual.

[benm]

My mechanic changed the oil for me. Basically you fill it until it starts dripping out the side. Mine was probably around the 3.5L mark.

[ken]

I have about 0.5L left. So, I have put about 3.2L. I will try to fill it become 3.6L today.

Thanks!

yeah give it a good 1000km or so.

i used to get crunches into 2nd, they went away after about a week of driving after putting in lightweight shockproof. then about a month later, shifts became nice and easy, i have a short shift kit and shifts used to be really tight, too tight, now its just nice.

[ken]

I have put another 0.4L into the gearbox. Now is totally 3.6L. I feel slightly better. But, still not too good. I will see how it goes after 1000km.

Is there any problem with the previous oil. I think it is auto trans oil.

Thanks!

[benm]

Fill it up until to spills out the side.

[DAMQIK GTS-T]

I doubt it would be Auto trans oil (your saying this cos its red?)

Skyline box oils I have seen range from brown to yellow to red most have been quite thin. you should how ever be able to tell from the smell if it's gear oil or trans oil.

[ken]

Yes, it's red. And also smell like auto trans oil. It's same smell as the auto trans oil in my friend's car (automatic laser).

[Duncan]

ken, I'm no expert in gearbox oils, but is it possible that a really thick oil was put in by the previous owner to hide a problem with the gearbox?

[MoonButt]

Duncan,

Having thicker oil usually hides a problem with the gearbox.

put a tube of nulon 70 in it. Works wonders.

I am not sure. But, before I change the oil. I have diffcult to change to 2nd gear when it's cold. And it is quite smooth when it's warm.

But, now even when it's warm, I can feel crunches when I change to 1st, 2nd and 3rd gear. (filled ~3.5-3.6L)

Worn clutch or clutch pedal adjustment needed???

[ken]

Yes, maybe the clutch adjustment problem. Everytime when I change gears, I will depress the clutch pedal all the way down. But, I only need to release it a little bit and the clutch start to engage.(car start to move)

And I found that the clutch fluid level is in the middle of the "max" and "min" mark. Should I put more clutch fluid in it? And what sort of fluid should I use to top up? Can it mix with different brands?

Or should I change all the fluid? if so, how to do it?

Thanks!

[MoonButt]

What I tend to do as a standard to my car is that " If the item and or fliud is unknown best to change it with a known item."

This way I am able to control what goes into the car and not to worry anymore. In the case of clutch and brake fliud fresh is best naturally. If the fluid has been sitting around in the garage or in a car for a few years they tend to absorb water leading to corrosion in the lines down the track.

Sorry to dig out an old thread, but i've just put in Redline blue into my gearbox and it feels crap (done about 400kays)...

any updates, ken? does yours feel better now, and how many kays did it take? Cheers

[Busky2k]

Hmm, perhaps you should have used Redline MTL or MT90. They are the ones that were designed from the start to give you better shifting, not Shockproof (even tho it does a good job too).

If it was ATF, it does give good shifting being really a hell thin viscocity, but it ****s up your box pretty badly after a while, because ATF does not contain the proper extreme additive protection that gears require.
