I am using the redline "cocktail" mix. After having tried quite a few different fluids actually, I found the redline cocktail mix to be the best,imo (evo 8 speed).

 

This sounds gooooooooood!!
How much does the gearbox need?

 

2 quarts of MT90 and 1 quart of MTL

(1 quart roughly equals 1 liter)

 

So it means the gearbox itself holds around 3 litres of oil ... I think I'll go for Redline too.

 

I just picked up my 05 Evo8 MR edition yesterday... I want to do a complete flush/fill aswell.. Can we be more specific with the 6speed oils.. This thread is a bit confusing..

 

For 5-speed, the oil type recommended is GL-3 or GL-4
For 6-speed, it's GL-4

 

Thank you... Just placed my order

 

Envy you man...that you can order stuff just like that...haha

 

 

I am having extreme difficulties in sourcing GL-4 soil for my tranny...
I can't even find Redline equiv in HK...

 

A question...would Toyota's GL-4 fit my Evo 9 GSR 6-speed tranny?

 

You can try it, your transmission won't explode or anything since it's a similar formula.

See how it feels after a few miles and if there are no issues with shifting and it feels okay when cold and hot, you're probably fine.

 

Finally I've sourced all oils...
For tranny oil, reluctantly I have to use Redline MT-85 as Diaqueen GL-4 is 100% not avabilable in HK and most on-line shops don't ship to HK...
I'll see what Redline feels like and decide my next move

 

A big question...please help
Since my E9 GSR is Jap spec with AYC...therefore I need to change the AYC oil.
I know the front diff uses LSD oil, what about the rear diff? Does it use AYC oil or LSD oil?

 

i have always used

Transfercase and rear diff: Mitsubishi OEM GL5 LSD Gear Oil Diaqueen (Part #3775610)
engine oil i use mobile 1 10-30
5 speed transmission = 2 quarts of redline mt90 1 quart of mtl
