Hi,

I have just purchased a 86 Audi 80 Auto. I understand these gearboxes are
susceptible to seal failure resulting in damage to the final drive gears.
Can anyone give me more info, what to look out for, should i change the
seals now, how many miles before the problem starts??

I got th transmission serviced and they overfilled it by about 300-400mls is
this bad?

Thanks.

The problem is that the seal between the transmission and differential
start to leak and the gear oil in the differential starts to mix with
the transmission fluid. Eventually the oil in the differential will
leak out so that there is no longer any lubication to the
differential. You will start to hear a whinning sound once the car
start moving.

I have had this happen to me. Fried the differiential at 75,000 miles.
The best thing to do is check the fluid to see if it is low. There is
a plug under the driver side axle shaft. If it is low fill it. If your
tranny fluid is black then change the seal. If it is fried get one
from the junk yard it's not worth a new one.
