Redline Shockproof Gear Oil In Getrag 6 Sp Box

[mxfly]

Well i've used this oil in my past cars and had good experiences with it.

Now i'm about to change the g/b oil in the GT-R, but someone has advised me it's not good to use it. He mentioned that I should use the Getrag oil, didnt even know they make it.

What are ppls thought?

Direct quote from their website:

Redline Lightweight ShockProof®

A unique gear oil designed to lubricate racing transmissions and transaxles which see serious loads (not recommended for most syncro-type transmissions). It has excellent low-temperature flow which allows easier shifting when cold. May be used to obtain maximum power transfer in racing differentials which do not see high temperatures. Similar to a 75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil.

Used in most road-racing differentials with moderate power and dogring racing transaxles.

That said, from what i have heard, it is a gb oil that is really only good for old and tired boxes where the synchro's have worn, and adding this oil provides a smoother change. The old "band aid for a bullet wound" type fix.

My advice: Dont use it.

This answer can be found via search. Shockproof should never be used in the Getrag 6 speeds, either should any other GL-4 75W-90 or similar style oil. The Getrag uses ATF believe it or not. I think the synthetic ATFs are ok (Transmax Z) just run a search and you'll find a definitive answer.

Thanks for the info guys.

the reason why, is that they use fibre synchros not brass. so it needs a atf type oil for them to work properly. same as a tremmec.

to use some 75w90 oil in getrag will cause some damage?? or just not work properly??

anyone??

160V fluid from Toyota is what you want to use (same getrag 6 speed gearbox in the Supra).

According to this link: http://www.turbosupras.com/pages/en/pages/technical/V160.htm

Castrol Transmax Z is ok as well.

i have no idea what oil in my box. its work fine, but just make a bit noise.

i did some search. the getrag gearbox is fine to have some mt90 oil or similer oil(like 70w90,70w80 75w85 etc) in it. but not the redline shockproof oil for sure.

is that right information?

The normal Redline gearoil should be fine as they meet GL-5 specs.

Redline will know - call them. I'd be very surprised if they tell you a gear oil is ok in place of ATF.

[Moodles2]

the Toyota 160V fluid realistically should be the only fluid going into the box, and Getrag 6 speeds aren't cheap to replace either.

And here's a quote from the Aus website which is under less legal restrictions compared to the USA in terms of oil usage, from http://www.redlineoil.com.au/oil-finder.asp :

Manual Gearbox Nissan 5 spd use 'Lightweight Shockproof', Getrag in R34 use 'Superlight Shockproof'. @ see handbook for Litres

I'm not recommending either way for a Getrag gearbox, just want to disagree for the entire it doesn't work with synchro's argument.
