Gear oil in the GYX transmission (6-speed manual)

Hello,

intended: G052911A. What are your experiences with other 75W-90 gear oils?

Can I safely use API GL-5 gear oil, or does the G052911A specification still have any special requirements, such as a long-life fill?
(The oil's lifespan extends until the gearbox fails )

Best regards, Rainer

Hello Rainer,
"Although the gear oil change was only 40,000 km ago, I can say that it still shifts very smoothly and is actually better than with the original oil, see: /viewtopic.php?t=15656&highlight=getriebe"

Hi,
I can only recommend Castrol TAF-X based on my own experience. Experienced occasional shifting difficulties at 350,000 km, and all those surveyed predicted gearbox failure...
I just switched to that one and now the transmission feels like a brand new car.

No, better: In the bottle on the shelf, the product has an expiration date.
Brutally knotted (and cut) in the gears, it will then "last forever".

Hey!?

My MQ250 (JYJ) and MQ350 (JMA) could also use an upgrade...

Thank you for the feedback! Seems to be rather uncritical.

Hi, Rainer

Rainer,

gehts um den grossen Audi ?
Take a look and report back.

Then I'll also do the same on the Golf, because it's already a bit rough after 134,000 km.

What should you think about when considering Slick50 or other MoS2 additives?
(if slick50 for switches (is) still available)

Hello,

The shifting works perfectly; I just want to remove the existing wear and apply fresh oil.

I don't want to use any additional additives because of potential "side effects" with the synchronization rings.

Hi, Rainer

Reasonably, I also say that gear oil, just like engine oil, needs to be changed at regular intervals.
What is your current mileage? When I got the AHF, I also filled it with TAF-X, and that made a huge difference compared to the standard VW oil.

I'm always wondering what exactly will happen if you don't use VW oil when changing the oil.

What do you expect from running (besides self-satisfaction)?

The wear on the synchronizing rings is already excessive. This
then adheres to the components. The rest stays stuck to the magnet.

no hard "particles" between the gears, less "dirt" in the gearbox, which results in less wear.
Mileage after a change would be approximately 120,000 km, meaning with the timing belt replacement. So, do you mean that it's unnecessary to use this gear, because there's no way it's going to get really dirty?

However, I always check the oil level and color, as the previous car (1998 A3 8L) had been underfilled from the factory. One could also hear that.

Hi, Rainer

The gear oil also wears and becomes old. This also changes the viscosity values, which has an impact on the shiftability.

Changing the gear oil is definitely a good idea.

I had a 1.9 TDI 90 PS VP TDI engine in my 1998 Golf IV, with a 5-speed manual transmission that had a traditional gear stick instead of the facelift version with a cable-operated system.

VW has always attributed jerky shifting to the gear linkage.
At KM-Stand 120.000 km, I changed the gear oil.

There were no visible residues found in the oil after refilling, but after refilling, the gearbox operated significantly better than before.
Specifically, the difference was significant at low temperatures.

I used a gear oil from Fuchs: TITAN SINTOPOID 75W-90

So, meinst du, es ist unnötig bei diesem Getriebe, weil es eigentlich keine Probleme geben wird?

It's a matter of personal preference. Obviously, the broth is no longer suitable. If you feel better, then switch to another one. It definitely won't hurt .

Short Story: In 2007, while returning from vacation, the pilot bearing and the gearbox input shaft seized up.
Wave renewed and the rest of the gearbox clinically clean.

Unfortunately, I had already disposed of the old oil. Then, unfortunately, it was impossible to determine which oil was originally in the engine. I then filled it with a fully synthetic 75/90 oil with the appropriate approvals.

Result: The gear shifted stiffly. The 1st and 2nd... Gang were particularly affected, even though no work was carried out during this wave.

Possible Cause: Incorrect or different oil, or lack of curd cheese (Schmand) between the synchron rings. But I didn't do anything else further down.

After approximately 10-15,000 kilometers, the situation has become more manageable.

Today, after 4 years and another 65,000 km, everything is back to normal.


What is the correct statement and what is incorrect?

I recently changed the gear oil in my old four-speed transmission, but the transmission already had over 300,000 km. I used VW gear oil. Unfortunately, it didn't make any difference in the shifting. I didn't want to continue like that. After a long investigation, my friend, who works for Scania, recommended using truck gear oil, as they had had good results with the oil in the same shifting problem. And guess what? Smooth, easy shifting, even when the transmission was cold or hot. But I have no idea what kind of oil it was.

Hello,

I filled TAF-X into my Passat 3B at approximately 150,000 km, and again recently at 300,000 km. I would rather concede that the shifting behavior has been improved.

When I changed the gear oil in my 1989 Passat B3 (approximately 310,000 km), I used the original VW gear oil. The remaining oil didn't look good, but there was no noticeable change in the gear's operation.

Therefore, for me, it's more about peace of mind - but that's something I value.

I changed the oil for the first time at 90,000 km, and it was quite cloudy at that point. Then, I changed it again at 180,000 km, and the oil I drained looked very similar to the original VW oil (which I bought for a ridiculously low price from the dealer's storage area, with an expiration date of 2013). After the first oil change, I noticed an improvement in the shifting behavior, especially when the car was cold. The second change brought absolutely nothing, both subjectively and objectively.

But it certainly won't cause any harm!
