Not an expert on troubleshooting that code, but problems with the torque converter clutch are in three general areas: electrical, hydraulic, or mechanical. Before replacing anything, I'd start with the electrical tests. I'm familiar with the A4LD, so if you have a '91-'94, I can help you with the electrical tests. The electrical is also easiest to test, so I think it's the best place to start. After the electrical checks out, then you need to check the insides of the transmission.

i agree with mrshorty. i've heard technicians say that an alternator not putting out enough voltage to keep the battery up will cause all kinds of weird things to happen. They will be trying to find something wrong with the transmission when it was entirely something else.

I wasn't thinking of the alternator as a possible problem, but it sounds like there could be a bigger issue.
1st quick test for an alternator. Put a voltmeter across the battery terminals (engine off) and note the voltage (Should be around 12 V). Start the engine. The voltage across the terminals should increase by a few volts (14-16 V). If the voltage doesn't increase, that indicates a fault in the charging system.
Another alternative is to get a charging system tester that can test it under load and such. Most parts houses have one and will test your charging system for nothing, in the hopes of selling a battery/alternator. They can usually test it out of the vehicle, too, if you pull the alternator and take it in.
Good luck
