R34 Getrag

[XKLABA]

I have been searching for about 45mins and everyone says what oil to use but not how much. I've put in 1.8-2ltr of transmax z with nulon G70 then out the filler hole it comes, is this right or is there a secrect to filling these up and if so how much should they take ? any help is apperciated

[Duncan]

Are you filling through the gearbox filler hole or gear shifter?

[XKLABA]

filler hole on side of box, just wondering cause the 32 takes just over 4ltrs the 34 takes 2ltrs ? , hoping someone can confirm it for me

Getrags seem to hold less, as they throw more oil around and are noisy (ATF based oil is so light).

I get about the same amount in there.

[XKLABA]

Ok thanks for that, looks like a regular service item then, every 10k, what oil do you use Sean?

[GTRsean]

Running transmax z, but I am going to try redline shockproof super light, this time.

Using gear oil in a box that requires ATF fluid, do you want to ruin your getrag?

I know alot about GTRs, Sean knows more,especialy about the mechanical side of things and if he says he is going to use that oil there is a good reason for it and he wouldn't do it lightly, he would have reseached it throughly.

I think ATF is a gear oil, just a very light grade

For getrag 6 speed manuals in the R34 and Toyoyta Supra - you have to use Transmax Z (auto) fluid or equiv.

ATF is closer to engine oil than it is to a gear oil, ATF is anything between 10W to 10W30, gear oil is closer to 75w-90 to 75w140 (shockproof light which is effectively a 75w140)

I was told shockproof super light, and or one of the special royal purple gbox oils, are a light oil. Reason is that the getrags run fibre lined synchros and they can burn out/be damaged by a thicker oil (that's what I was told a while back).

Also Redline claims on the back of it's container that it has a viscosity of 30 but offers the protection of a much thicker oil...something like that.

Getrags are cheap, aren't they

Seeeeeeeee, reseach

Yeah dime a dozen

I've read superlight has been recommended by redline for getrag 6 speed, it's yellow though, light is blue (aka smurfsblood)

[GTRsean]

I wasn't told by some keyboard warrior, I talked to a well known workshop that has specialised in GTRs as well as Z's for years and years, and 2 gearbox specialists. Also some of the US forums, but just for info.

I used smurfs blood, redline shock proof (Blue stuff) in the GTR......32.

Blew 3rd gear out 3 weeks later....
