Which RedLine Oil

[nedb]

I'm going to change the diff and the auto gearbox oil in the next few days and i'm just wondering what other ppl have used or think what would be better. I've decided to go with RedLine products as i dont mind spending a lil bit extra for the quality.

At the moment i'm thinking heavy shockproof for the diff and i haven't decided which one for the gearbox. I'm thinking between the Hi Temp ATF and the Racing ATF.

Hi Temp would give me smoother gear changes than the Racing one but for the better shift performance i'm probably leaning towards the Racing ATF.

They say that the Racing one doesn't have any sliping additives so i'm not sure if it would be recommended for the R32 automatic gearbox.

Help please!!

Use lightweight shockproof in the diff. The heavy stuff is too thick.

As for ATF, just stick with the Synthetic D4 ATF. The Hi Temp stuff isnt really worth payin extra for unless you want piece of mind. The Racing ATF will most likely prematurely wear out your clutch packs because it is not Dexron III approved.

I went with Heavy shockproof for the diff and its fine. I was told if i get any clanking noise from the diff to come back and they'll put some slipping additive to fix the problem - but there was no need for that.

As for the Auto gearbox, i haven't done it yet. I haven't had time and i'm still undecided on what to use. I was gonna go with Hi Temp for the piece of mind or Racing oil for that extra oomph but not sure of the side effects.

Has anyone used any of them???

paully: Is this for the Auto gerbox?

I used lightweight shockproof in my diff and it seems to have fixed the occasional one wheel spin I was getting.

I also put Redline High Temp ATF in the auto and it sharpened the shifting a little but not heaps because I didn't have the pump you need to get the fluid out of the torque converter.

I think I'll go for Racing ATF next time but I want to make sure I've got some cash in reserve before I do it just in case. There's not many people know about R34 auto boxes.

nah. i got a manual.

didnt think there would be a difference for auto and manuals.

guess im wrong.

I just got of the phone with one of the guys from Australan Distributors for RedLine Oils and he put a whole new spin on the situation.

His opinion is that more slipping in the automatic gearbox will give you a smoother ride BUT it also increases the gearbox wear.

He strongly recommends the Racing ATF, with no slipping additives, for the better shift response and loger life of the gearbox as long as i don't mind the jerk between the gear changes, which would feel like a manual driven car.

This is a 180 degree spin around from what i was thinking.

His name is John.

Any thoughts on this?

Thats an interesting find. Maybe hes right, but I dont really like the idea of putting non specified fluids into something expensive like an auto tranny. His analogy is sorta like slipping a clutch. Slip and ride a clutch like 17 yo n00b in a festiva, then the clutch wont last. I suppose you can try the Racing ATF and check the shifting, but I reckon the HiTemp or D4 stuff is still the way to go personally...

I spoke to that guy too but I wish I had some other knowledge. Wait... doh! My dad is a mechanic...

ok just called him.

He said it would make sense that the Racing ATF with no slipperiness additives would produce less wear of your bands and such. If anything it might put more stress on your planetary gear set but due to their design they are unlikely to be a weak point. If you know how they work you will understand.

[nedb]

So would that mean there would be no major side effects with using the Racing ATF apart from being less smooth on gear changes?

[Abo Bob]

That's the theory.
