So, my transmission needs to be replaced on my 2003 RS6 (80,000 miles). Thankfully, I have warranty insurance that's covering the costs for that, which means my engine is being pulled on someone else's dime. Is there anything I should ask to have done, while the engine is out? I'm mostly looking for prophylactic replacement of parts that might fail and require expensive labor costs to get at.

For example, is it worth replacing the original turbos, even just with newer OEM replacements? I'm not really looking for performance improvements, since drive train seems challenged with the original power on these beasts.

i need to let the mechanic know in the next ay or two if I want anything added to the planned work...
