Read this post from fixya.

recheck bolts on bell starter and converter. check universal joints. loose flywheel bolts could cause cracks in flywheel. remove dust cover when shaking see if flywheel is moving back and forward

The solenoid engages the lockup part of the torque converter.
So it could be either one.
The solenoid would need to be tested.

I would lean toward the torque converter solenoid or something in the wiring. Not the ECM.
You might be able to unplug the solenoid and recheck it.

Basicly just remove the bolts in the transmission oil pan, make sure you have a drain pan under it and leave a couple bolts in, loosen the remining bolts and let the oil drain then loosen and remove them slowly as oil will be draining out while you are doing it.

Change the filter and after cleaning the pan install a new gasket and put it back on. Do not tighten the bolts too tight because it will distort the gasket and it will leak.

Pour about 5 quarts of transmission fluid in the trannsmission and start it up, look for leaks, and finish filling it to the cold line on the dip stick. If there are no leaks run until its warmed up and make sure the fluid level is at the full hot line on the stick.

There is really no way to drain the converter.

The code means the computer can not activate the lock-up torque converter. The problem could be the converter, or the solenoid that controls it.

Sounds very broke! the axle are ok put out the drive axle and check the spline in maybe gone!

Audi code P0741 Torque Converter Clutch Circuit Performance or Stuck Off, THIS IS IN MOST CASES A STUCK TORQUE CONVERTER LOCK UP CLUTCH, U MAY NOT EVEN NOTICE THIS AS ALL GEARS WILL WORK JUST NO TORQUE CONVERTER LOCK UP, U WILL NEED TO VERIFY THE TORQUE CONVERTER CLUTCH CIRCUIT IS OK AND IF SO REPLACE THE TRANSMISSION TORQUE CONVERTER.
