Manual Rs4s Gearbox Oil

[mr fusion]

Hi all,

I'm really sorry if this has been posted. I did a search but couldn't find anything stagea-specific.

I am gathering parts for my first full service on my '99 Stagea RS4S and am unsure which oil I should get for the manual gearbox. I did some reading and found 3 different castrol oils to use:

CASTROL SYNTRAX 75W-90

CASTROL SYNTRANS 75W-85

CASTROL VMX 80

I'm guessing the VMX80 is the run of the mill oil and maybe the syntrans is the way to go. Can anyone confirm that? And how much do I need? About 4 litres?

Thanks, and sorry again if this has been posted already,

Matt

I'm using redline shockproof lightweight in my (R33 GTR) box.

- changing all gearfluids today on my M35. - although i dont believe it applies to c34's gearoil and only m35 infiniti's

will keep people updated on how that goes.

10 litres of matic-j for gearbox and transfer case. (need to flush any dextron III out of there with a pump so probably waste at least a litre)

1 litre of matic D - for power steering.

1 litre of .3 nissan brake fluid.

new belts!

the only thing ive forgotten is diff oil! probably use redline for that!

For brake fluid: Motul RB600

I use the same in my R32 GTR box.

As ive only been manual for <3,000k's ive only used one oil, that being a penrite product 75-90W fully syn, all was cool till first drive on freeway last week and ive realised at high rpm I've got a crunch into 4th.

perhaps I should try redline shockproof lightweight?

did you use a 32gtr gearbox? From what I've heard, a crunch into 4th is pretty normal for them

did use a 32R box yes. No crunch is "normal" might be a common issue but not normal.

yeah, normal was the wrong word to use. Either way, it's not an unusual thing, apparently only really happens when changing into 4th quickly, especially at high revs.

There's a good chance the redline shockproof will get rid of the noise, but it won't actually fix the problem.
