Gearbox oil

[andrewwilson8]

Look at this guide here on how to do it yourself - http://www.audipages.com/Tech_Articles/ ... icing.html

very interesting indeed.

just printing a copy now to fax to the garage that ruined my gearbox.

Just had Grizz do mine with a service etc , cleaned the magnets , put loads of oil in etc , didnt ask how they checked the levels though , just relied on the man , and he is , ...The Man !

Is this guide for the S8 ok for the RS6? As far as I can tell, the gearbox looks the same? What about other ancilliaries?

@andrewwilson8: I would have thought that the garage's professional liability insurance will cover this. You may need to get an independant expert to drain your gearbox and measure the amount of oil in it. Either that or try and work something out with warranty. Personally, I'd use this as an excuse to look at a manual gearbox conversion (sound of can of worms opening )

Similiar story to mine, got the oil changed by the local stealers and 2 weeks later gearbox packed up big style ! They took the car back to investigate which was witnessed by my motor assessor. He logged all the errors by the garage in the manner which they checked & topped up the oil and also took an oil sample from the box. So not only was there an issue with the level but the results from the sample show that the incorrect oil was used ! This is now gone legal but should be sorted soon enough.
Would definitely get an assessor involved ( but be carefull who as i have heard stories about some assessors being rewarded for siding with the garage ).

Would use nothing other than Redline oil, smoother gear changes and a far better oil blend than anything from Audi, same story for the rear diff.

The fluid I use provides higher torque converter efficiency at higher temperatures (which is needed for remapped RS6's) and provides better film strength when compared to petroleum ATFs, reducing gear wear considerably and has improved the shift no end on my REVO'd RS (no gearbox map)

[Corey]

One other point to note, whilst the fluid is out of the 'box, have a good check on the rear output seal, have seen quite a few that have been leaking and needing the seal replacing, worth doing whilst in the area.

manual conversion? tell me more!

[Shoppinit]

I don't think there are any. Or maybe MTM do one for megabucks. I never figured out why though, because as far as I can see (which, I admit, isn't very far at all) an S8 or S6 manual box could fit? Would be a nasty job, though.

[andrewwilson8]

JByrne: Sounds like good advice. My fear is that they will change the oil again, but properly so that it runs ok then expect me to go away happy.

sadly i fear that this will be a very shortlived solution and in 1000 miles time it will pack up completely, and they will be making out it is no longer anything to do with them.

If the gearbox has been driven 100miles with only 3 or 4 litres of oil in it, is it going to be terminally damaged? If the answer is definately yes then i need to pursue a new box immediately, and not be fobbed off.

Yes the garage should have public liability insurance, as a last resort.

it may well do, the transmission service guide posted earlier was for an S8 and that all looked the same underneath. kinda dark and oily. . .

[shaunrs6]

can grizz or somebody confirm that the gearbox oil change guide is the correct way to do it??

but how does this empty the torque converter??

[Shoppinit]

but how does this empty the torque converter??

I was just wondering this also...

[Shoppinit]

It looks like the torque convertor uses the same ATF as the box, but I can't see a way to drain it without removing it completely. Only thing I can think of is "purging" by changing the ATF several times. $$$

[shaunrs6]

the torque converter does use the same oil,and yes thats the only way i can think to make the torque converter empty itself,but would be great for feedback to confirm this?

[grizz]

That's how we it , The only way to flush it is to use a by pass system that you connect to the oil cooler pipes.
