Transmission questions
As I'll be changing the transmission fluid on my FL D2 4.2 very soon, I had a couple of questions that can hopefully be answered. . . .
Is the fluid change procedure on Audi pages the one I should follow or are there any others? The reason I ask is because there is what seems to be an official ZF video on YouTube which details the procedure slightly differently. I just wondered if anyone had had experience of this? Secondly, I can buy genuine fluid and parts from the parts store and was wondering if they are the same as Audi (I assume they are so should be fine)? Any feedback would be greatly appreciated. Many thanks.

I think you need special equipment for this on a D2 and so it's a professional job. You need the machine that effectively flushes the box (referred to on here as a 'squirty, pumpy, sucky thing' or words to that effect) that a good ZF specialist would own.
There are tales of the oil simply being changed and boxes failing shortly afterwards because of 'muck' being disturbed and not flushed out. The 'Glasgow mafia' uses a company called Mackies and the cost is around £150. They recommend that this is done annually! Depending on your location (good idea to include that in your profile) someone on here will be able to recommend a suitable company I'm sure.

Ahh yes, that info would be useful on my profile.
I understand that a full flush would be beneficial as it would replace all the fluid in the transmission, and when doing a drain and fill whilst changing the filter and seal, only around half of the fluid gets changed as the rest of the fluid stays in the torque converter. Reading the info on Audi pages (and from other sources), the drain and fill procedure seems very beneficial. As long as it is carried out in the correct way and at the correct temperature. I would be interested to know (if someone could tell me that would be brilliant) if anyone local to me would have the facilities to be able to carry out a full transmission flush. . . . . . .

You may have already seen the info in the sticky at the head of this section but there is a lot of info there including ZF specialist locations.

Thank you. I did have a full read through and called a few of the centres but most of them only supply parts. Chester transmissions seem to have a good reputation (although not on the list), it's just a bit of a drive from me. Not that that's a problem in the 8 though

One thing I do find frustrating is the amount of conflicting opinions regarding the effectiveness of a service and process in which it's carried out. Some suggest a full flush is the only way while others say it's simply not possible to carry out a full flush due to the design.
Quite difficult to know what route to take. I'll probably compete the job (drain and fill with filter and seals) myself with VCDS monitoring the fluid temp during the process.

Where do they say full flush is not possible?
Again, depends on definition of 'full' flush. Couple of drops will always be left. If you have choice between normal procedure and the 'plus service' where they do oil change with a machine by connecting it to oil cooler line just go for second option as in this case they will change almost everything in the system. Tell us what your concerns are.

Well I've been contacting local-ish transmission specialists to see if anyone can offer a full flush service rather than a basic drain and fill. The people I've spoken to so far can't do the former. One company (TES transmissions in Wiltshire) said it's not possible to fully flush the system due to the design (solenoids, torque converter etc.) Surely the process of gear selection will ensure full flushing of the transmission?
Then there's the discussion of what fluid to use. . . . Lifeguard 5, esso, mobil, imported fluid from Canada (as used by Chester)? Both esso and Mobil are owned by ExxonMobil so I would guess both products are the same. I'm inclined to use ZF's own product for piece of mind (even though it is almost twice the price) but transmission specialists would be happy to use something else. . . . It's amazing how much info is on this subject on the net with seemingly no clear answers. Maybe a call to ZF will be able to shed some light on the situation. After all they are the ones who designed the transmission in the first place.

When I went to Chester I purchased all parts including fluid myself from Audi. When I talked to them on the phone they asked me (twice) if my fluid is genuine Audi.
Did you talk to them? Are they saying they now import fluid from Canada?
