trouble shooting audi 2001 a4 automatic gearbox
Discussion
hie guys can u help me out here im working on ths gearbox e driver says the car was moving normal n then it started behaving like its running out of fuel jerking kind of way then he turned it off,when he got it running again it was only in 1st gear not goin above 10km/h untill she gave up n they towed it to the wrkshop ive checked the clutches are ok n there r no broken gears or shafts what might be the problem
IF its an early CVT, the clutch pack was modified by Audi to include an extra plate due to jerky failures. You will need to check with Audi.
When was the trans oil and filter last changed?
Is the oil clean? Dirty oil can become conductive which plays havoc with the mechatronics in the 'box as they are immersed in the oil.
Clutch plate packs about £1k

If your car judders on gentle acceleration then the most likely culprit/fix is a 6-7 clutch plate conversion or a new input shaft, and an update. Don't get this done anywhere else other than a main dealer. Gearbox repairers are not able to recode the gearbox ECU for 7 plates.
If you have juddering as you are coming to a stop, it is most likely to be a valve chest. No reason why any specialist or person with a ramp can't do this as it is straight forward and should not cause any grief, although they will need the special tool to set the correct oil level for the box. Remember that you have just paid the best part of a grand for a valve chest so its not worth going to any one that has said they will be able to sort it out without telling you how they are going to do it.
If the car has flashing gearbox lights it is most likely a gearbox ECU. Again, the best part of £1k for the part and anyone can do it. Just make sure that the base settings are adapted correctly which can only be done by someone with genuine guided fault finding equipment.
If the car has flashing lights and no drive, you are looking at a gearbox failure. Normally an 'output speed sensor 2' fault will be stored. This means a non servicable part of the gearbox has failed and is not repairable.

Methinks your 'box is goosed.
