Thank you for the link. I've also been experiencing those rumbling noises when turning sharply for a while now, and I've been attributing it to the power steering pump.

By the way, the reference to the 726 oil is no longer included in the more recent versions of the checklist for waste-to-energy plants, as far as I know.

Brief update:

Unfortunately, nothing happened this weekend with the change, because that stupid socket hasn't arrived yet. The changeover won't happen until the weekend after next; I'll let you know the result then.

Hello,

There is news.

This weekend, I finally managed to change the transmission oil. There was definitely enough in there; it immediately poured out of the fill hole. The stuff was extremely thin, labeled as 75W-90. Well, at least it drained quickly. Filling it up was a bit tricky because the car wasn't perfectly level on the lift, so the last 150 ml just wouldn't go in. Okay, so let's bring it down from the stage again, adjust the recording heads so that it rises slightly at the front, and then fill in the rest.

The Nordec socket from Egay doesn't fit very well; it's quite unsettling when using it on an aluminum screw...

I've driven about 40 kilometers since then.

Changes:

- The transmission is subjectively a bit quieter.
- The clicking sound that occurred when shifting gears in a warm transmission and driving with the window open in the underground garage has completely disappeared.
- So far, no more squealing when taking tight turns in the underground garage.
- Shifting from 2nd to 3rd gear at 4,000 RPM and with a warm transmission is almost smooth again, but unfortunately, not quite. However, there's a noticeable improvement compared to before. I'm curious to see if things will improve further. According to Matthias, it takes a few hundred kilometers before you start to notice a significant improvement.

Hi Roger,

Could you perhaps visually compare the viscosity of the old oil with a small, unused sample of the new oil, for example, by tilting them in a clear container?
That would be interesting, in my opinion, with regard to oil wear.

Unfortunately, that's no longer the case. The old oil used to drain into a basin and was then directly disposed of in a large waste oil container. The subjective comparison of viscosity was somewhat flawed anyway, because the old oil had been warmed up from a drive of about 10 km, while the new oil was noticeably cooler. It drained just as quickly as warm engine oil would.

The new oil was poured in through a funnel and a hose with an approximate inner diameter of 10 mm, which took quite a while. That's when you could tell that it was gear oil, not engine oil.

Due to the noticeable differences in shifting behavior, I would no longer recommend using oil that is supposed to last the entire lifespan of the transmission.
"60,000 km is, in my opinion, already quite a high mileage."

Hi,

...for 75W-90, extremely thin viscosity.

What viscosity, in your opinion, should a 75W-90 gear oil be? If you base your understanding on the viscosity classes of motor oil, then it should be as "thick" as candle wax .
That's not the case! A 75W-90 gear oil is roughly comparable to a 0W-40 engine oil in terms of viscosity.
So, don't compare apples and oranges...

Regards,
Sure, here is the translation of the text from German to English:

Hello,
What type of transmission fluid are you using now?
The G052 726 A2 (for a 5-speed manual transmission for gasoline engines) or the G052 171 A2, which is intended for the ERF transmission, are also used for the initial fill.

The 171.

Update:

The itching is now completely gone .

...great, a nice oil change... as I said, I was also satisfied. What did the oil look like that came out? Do you remember the photo I sent you? "Worse?"

Photo ??
*scratching head*
-> or my Alzheimer's?

No.

But mine was still translucent, with a consistency similar to weak coffee.
I would say it's like using half the amount of coffee when brewing .

Amazing, then at least the Göl used in that process is something like a high-tech broth with a delayed effect .

The more puzzling it is that VAG still insists on the fixed maintenance intervals... or perhaps, in order to sell annoyed customers a new transmission instead of a simple oil change?

Well, mine was more like coffee with half the amount of water... it seems there are differences.

Furthermore, mine is now approaching 25,000 km and it still looks brand new... I checked the fluid level and noticed this... it seems all the dirt is now out .

Hi,

"My transmission gets warm when shifting into 3rd gear." This whole situation is incredibly frustrating, which probably signals that I should seriously consider switching my health insurance provider.

Are there current oil recommendations for the ERF?
Sure, I can also source from the open market.

Hello,
I'm not sure if this relates to the ERF, but I've used Pennzoil and I'm still getting very good results with it (currently at 124,000 km). Shifts smoother than before the oil change.

Hello, Yesterday, I changed the oil in a 5-speed manual transmission (115,000 km). The original oil was a light brown-gray color, and there was a very thin, similarly colored deposit on the screws. Everything looked good overall. Then, pour in Pennzoil 75W-90... haithamina

The costs were marginal compared to VW oils.
Sure, here is the translation of the text from German to English:

"So long,"
I am unable to translate "haithamina" because it does not appear to be a word or phrase in the German language. It may be a misspelling, a proper noun, or a term from a specialized field. If you can provide more context or clarify the intended meaning, I would be happy to assist you with the translation.

Thank you.

But I think I'll probably give Castrol TAF-X a try. Based on what the StarDoc recommends for MT, it's probably not a bad choice.

It seems that the gearbox (GÖL) in 6-speed transmissions with 60,000 km (approximately 37,000 miles) of mileage is often completely failing. This particular gearbox has 73,000 km (approximately 45,000 miles) on it, and it started making noise after a slightly faster highway drive, followed by upshifting to 3rd gear while the transmission was warm. It's no fun always having to count "21, 22" when you want to shift gears without brushing your teeth.

I can't quite recall, but do both screws on the gearbox need to be replaced?
