A8 Gearbox Problems

Easiest way to check is to put it into tip mode then look and see what shows on the driver Information Display between the rev counter and speedo. It'll show 4 3 2 1 for a for speed and 5 4 3 2 1 for a five (logically enough!!!).

As Ska says, first thing to try is a filter and fluid change. If nothing else it will give you an idea of how the transmission is. If the fluid smells burnt, has lots of particles in it or is brown (dark brown) in colour then there may be a big problem in the box. If it doesn't smell burnt and is relatively clear and light reddish brown then it would suggest an issue with a sticking solenoid perhaps.

Good luck!

You have mail 169144-ok.gif

The stealer is your best bet although www.vagparts.com can get hold of the parts as well but it might take a little longer.

Also seeing as your doing the first ATF change ever for the car then drop the sump clean it out including the magnets and leave it to drain over night. Once topped up correctly the next day I would do another ATF only change a couple of days later. I infact did 3 in one year after audi stealership did one initially which bought about massive slipping and the almighty kick in the rear when it finally engaged. Oh and I think the equivelent to friction plates is the torque converter on Auto's

Good luck and keep us posted wink.gif

IIRC the filter/strainer is around £35, the sump gasket around £14 and the seal around £4ish; oh and the ATF is £8.47 per litre (you'll need about 6 for the first time alone).

Vagparts are normally quite good at getting back on their email but you can give 'em a call just have your engine and Gbox code (on lable on the inside of spare wheel well) handy or your chassis number n/s front windscreen 169144-ok.gif

Ahh the joys of buying a car off ebay - btdt, and yes the seller lied has ass off.

Anyway, its not all bad. Recently did an oil change on mine just after buying it since it had never been done (car has 80k miles). Got the bits from stealer then went over the procedure from www.audipages.com with a local indy. The parts were

Sump gasket - £14.97

Oil filter - £23.17

Filter gasket - £1.27

Plus 7 litres of oil at £7.81/litre

Those prices dont include vat.

Got it done for £160 all in. Going to do another soon but will do it myself. The procedure in audipages is easy to follow and not technical.

If you dont get any joy from the seller make this the first thing you try. It has worked for a lot of folks in the past.

oh dear oh dear.. I'm starting to panic.

my mechanics nearly put valvoline dexronIII, mercon (red color)

I'm planning to buy the oil for them myself, as I cant trust them anymore..

If I go to dealers and say: I need G-052-162-A2 ATF Fluid (this code is from the audipages), will I get the right one? Or this code is valid in USA only?

BTW: the old oil was as black as in those audipages photos smile.gif

Sorry to hear that. But just wanted to ask you, does it do what you originally described [on page 10 of this thread] when the car is totally cold? My gearbox oil needs changing very soon, and starts to play up only if it gets very hot (and I mean really hot, as in on a hot, sunny day and ahem, very vigourous driving). From cold, the gearchanges are smoooooooth and jerk-free. As the weather is now getting quite cold, it'd be an ideal opportunity to test this theory.

Hmm, well apart from it being something more ominous, it could be that perhaps the gearbox oil was not topped up fully? See THIS Tyresmoke post which proves that even after a gearbox service, unless the gearbox oil is topped up properly, there will still be problems. Only when the gearbox oil was correctly topped up did the person benefit from the ATF service. Beyond that, did you eventually resolve the confusion regarding the oil itself (colour, part no. etc.)?

Good point about the topping up of oil mate. The car has been left over the weekend to drain. At the beginning they put 4 litres. Took the car for a drive and then added another 1 liter. They said the level was OK, but your link given states 6.5litres should go in. Thanks mate! I'll go and see my mechanics again for a level check.

About the oil confusion: They have apologized for that. When they were ordering the oil they haven't said it's for a tiptronic gearbox. That's what theirs excuse was smile.gif

I still got a little hope smile.gif

Hopefully you can get it sorted. Worst case maybe you can source a replacement gearbox from IT S8 from one of the cars he is breaking.....

It would probably be cheaper to get a used box in good working order than rebuild a damaged one ?

Do you know what would be the average price for the used gearbox?

To put in perspective, the last 3.7 pre facelift 2wd box we sold went for £800 inc 3 month warranty.... We dont have any others at the moment.

This is the first I've seen of this thread (must have been napping) but I have to say the symptoms dont sound good. Oil changes can help prevent gearbox failures, but it sounds like this one is beyond that. If it were me, I'd take it to a proper gearbox specialist PDQ.

We have a guy we use for diagnosing boxes, he charges us for taking a look at it, then if its easy fix he does it for a few hundred quid more - but he always always stresses to us to get the car to him ASAP and dont drive it unless unavoidable to increase his chances of saving the patient..

A donor box is good if you can (a) find one and (b) guarantee it is good and wont fail after a thousand miles...

If you're intending to keep the car long term, I would advise consider paying for a proper overhaul, get a lengthy warranty with it and put it to bed as a job over and done with.... All the boxes go eventually, just a matter of time.

Sold the car yesterday.. Just fed up of those problems.. The funniest think: I found my car in the gallery: the one with 20' chrome rims, lcds in the headrests,sat nav, blue pearl laugh.gif

never mind, the guy was happy to have the car as it is.

He might be going another 50k miles, but i didn't want to take that risk. Thank you so much guys for everything. You are the most helpful people I ever met in forums. Regards, Andrew
