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???

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.

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.

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      By Rezz · Posted

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
