Questions on What to do if TC is going bad

[Mikefo]

Hi guys, I have a 03 RS6 with 44k on it now. Its been trouble free generally. Replaced the emission hoses, and a few sensors. Just got my first TC error code p1624. A few weeks ago the transmission gave me a clunk and the cars computer went out until I reset it. Not sure its related. I cleared the codes. Drives fine for now. Its a low VIN # so I suspect the TC life will be short. Question: If it is the TC, what else should I do besides replace the TC? The car is bone stock except for a set of 19 BBS wheels. What has to happen to get to the TC? Should I replace the O2 sensors if it makes them easier to get to them? Is there a brand of TC that is superior to OEM? Does driving a TC on its way out damage the transmission? Looking for any help / guidance on what to do if it TC gives me more codes or effects the drivability in any way? I really like the car and plan to keep it for another 40k or so. Since I put 6k per year that a long time. I don't mind spending a little money to maintain it. Just want to do everything efficiently.

Thanks for your help
Mike

I replaced the TC on my 40k Daytona.

2 weeks later I replaced the TC and transmission.

Your mileage may vary

I will have a new Audi updated trans w40k miles in a few weeks. Coming out for a built up 517 trans.

Most new TC's are of same quality, trans varies by builder. Do both now...

Sensors vary, I've replaced good old ones, only to have a new one fail. So not the biggest fan on replacing if not failing...take a look over all seals and hoses, vacuum lines, maybe replace some.

I replaced the TC on my 80k Mugello Blue.

8 months later I replaced the TC and transmission.
