Default Slipping tranny

Aight.. Surfed the search for about an hour now and am giving up.
My cousin has an A6 with the 4.2 auto, 2000.
Out of the blue it started to slip, was searching for gears and now is in limp mode. It slips less in limp mode. It happened suddenly so I am thinking it was electronic that went bad. We have a Vagcom on the way but I wanted to do some research with "experienced folks" to know what to look for. Ya know like what wires to look for that may have come loose. Just did the timing belt about 2 months ago. Suggestions?

He changed the filter so the fluid is right. I know that since it has been in limp mode that it is working better. But you are saying completely change the fluid? Suggestions on the service?

I trust no one but myself. How do you know that the fluid level is correct?

As others have said, check fluid level first, make sure correct fluid was used, cannot use anything other than Audi fluid, then check for codes. Mine was done also, but the Audi dealer (who shall remain nameless but they were owned by last years LMP2 factoryPorsche team) messed up the first time and had to re-do the whole job. It was in limp mode sitting in their driveway supposedly ready to pick up. Hair raising experience to say the least.

The slipping and such actually started before he did the oil change and all. But I will make sure he double checks the fluid again.
