6 speed manual identification

[jj94tt]

Transmission identification codes: So I am trying to determine what fluid to get for my 6spd manual (early 2005 B6 A4). I found the build code sticker and the line of interest says "AVK ETS GJV". There seems to be about 1000 different trans codes out there, but from what I can tell, mine boils down to an 02x? Can someone please confirm? Fuchs guide recommends OEM oil for this application; notes that it is a special product.

Is the code from the sticker enough for a positive id (if I am confident it hasn't been swapped)? Or should I be looking for a casting number?

Thanks.

Pretty sure 3Qts. your choice of synthetic 75w-90 GL4 (Motul 300, Redline MT-90, etc.)

AVK - Engine Code.
ETS - Rear Differential Code.
GJV - Transmission Code.

GJV is an 02X transmission.

02X 6 speed Is a GJV trans code.Should take 3.5Liters of fluid.Alot of people have had good luck with amsoil products or motul.However the oem P/N of the fluid is G055532A2.Cant really go wrong oem fluid is about $20 a quart.Either way not expensive.

You have an 02X. I tried MT-90 in mine and went back to the factory fill. Old Guy has some recommendations on fluid in some other threads.

Thanks guys.

I was just about convinced to use Ravenol from OGs threads (I could be wrong, but I am not sure OG has an 02x)... then the Motul guy showed up and was pretty convincing. But, I can't shake the notion that the 02x is somehow different. ECS has a kit that says, "For vehicles with 6-speed manual transmission only" (ironically the image shows pn G052171A2)... and Fuchs oil finder webapp says, "Special product, please use the original OEM part", for the 02x 6 speed.

Most catalogs just list "Manual"... so you get all kinds of part numbers: G052171A2, G052911A2, G055532A2, and even G070726A2. So... it's annoyingly ambiguous and confusing.

It seems like the consensus is just to use a GL4 fluid... but then, why all the various fluids from the factory? I think I'll just find some G055532A2 and call it a day.

ETKA says it can take G 052 911 A2. Fuchs claims their product for this is Titan SintoFluid SAE 75w80.

02X is a type of transmission. GJV is a version of it. As is GJW in the 1.8T. OP likely has a GJV.

Thanks guys.

Convincing about what?
We all tried Motul Gear 300 and it was shit. I think that's pretty convincing.

Yes, I don't understand the Fuchs website. I couldn't find anything listed under B6 A4, so I simply thought to myself, "I'll look up the B7 A4, since ALL of those are post-04, and ALL of those 6MT's came with an 02X-type. As did the later B6. Just maybe with different gear ratios."
And for the B7, they list G 052 911 A2, Fuchs Titan SintoFluid SAE 75w80.

Which I doubt is as bad for my transmission as putting in vegetable oil.

I don't know. Maybe people in cold-weather environments like Canada, or even less-so the UK, complained to Audi of rough feeling, so they picked something thin.
But supposedly the one you list is too thin and like water. At least that's what I read on Audi-Sport.net, a UK forum.
I guess you're welcome to try it, and if it sucks, then something else next to replace it.

ETKA also lists G 052 911 A2 for 5-speed manual, and early 01E 6-speeds.
So I don't know what about the 02X would make it so different that it needs something else.
The center portion of the transmission case is probably aluminum, instead of maybe iron on an 01E, which might handle more power in a B5 S4 and older Audi's.
Unless I'm mistaken.

From what I have seen, that is the correct PN for a 02X in a B6. At ECS it's about $18.51 for a liter bottle (G055532A2). On my six speed swap I ran the fluid that Spike mentioned (G052911A2), at ECS it's about $26.49 a bottle. Reading the labels, both list alkenyl amine but the more expensive lube lists Thiadiazole. I never heard of that before, so I looked it up.

It has now been found that, as well as being suitable antioxidants and anti-wear and extreme-pressure additives, certain 2,5-dimercapto-1,3,4-thiadiazoles which are both phosphorus-free and ashless are also capable of effectively protecting metal parts, including copper in particular, from corrosion and the corrosive effect of sulfur, i.e. they have a particularly broad polyvalent action as additives for lubricants or hydraulic oils.

Both PN's are compatible, it appears that G052911A2 is a higher end lube that offers better gear protection as well as corrosion protection of the synchros. Basically a way to get excellent hypoid gear protection of EP additives like sulfur and be compatible with the synchros at the same time. I have run both and in my experience the G055532A2 had more wear metal in it between changes (B5 Passat).

Both work, my theory is that the G052911A2 is a higher performing lube, it's reasonable that something has to justify the 40% greater price. I am curious to compare G055532A2 to my current gear lube. My 02X is a tiny bit notchy when cold. The G052911A2 definitely shifts better than the Redline I tried (that got used as a flush lube).

ETKA lists G055532A2 for GJV

*Tried* to be convincing. :)

The real debate was between Ravenol, Fuchs, and OEM. OEM seems to be the safe bet - but then identifying the correct OEM was the purpose of this thread.


Bottom line: OEM spec for the 02x/GJV is G055532A2.

But G052911A2, is spec for B7 02x manuals, which are assumed to be similar... Fuchs claims Titan SintoFluid SAE 75w80 is comparable to G052911A2. I wonder if the Fuchs has Thiadiazole?

[blitz2190]

Don't know about all the other oils but I've put 100k on the 01a with 75w-90 amsoil severe gear synthetic in it year round, shifts smooth and runs great in NH winters. About 50k on the 01e with the same oil and same temps, shifts and runs great.

You have an 02X. I tried MT-90 in mine and went back to the factory fill. Old Guy has some recommendations on fluid in some other threads.

I also tried the MT-90, got sick of the crappy cold weather shifting and went to Ravenol 75W-80 after seeing OG's recommendation. It performs worlds better in the cold and year round (used to have a slight 3rd gear grind with the MT90).

i went with some mobil1 75w-90, mixed in some ceratec, quites it right down

I heard Ceratec will interfere with proper synchronizer function.

[shoemaker617]

ive used it in my 5speed and now have it in my 6speed. Shifts like butter. I have a pressurized oil filler so i pre-mixed it before putting it in
