My A4 S-line as started to shudder during hard acceleration to the point that I have to take off without giving it much gas. It only has 93k miles on it but read online that it is typical for the CVT transmission to fail and was news to me until I researched it. I am not trying to find out how to locate a used one and make sure that it matches the car. If anyone knows the best way to buy from a parts house and make sure I get the right one I would appreciate some input. I would assume there are certain transmission #'s that I can match up to make sure I buy the right one for B7 S-line AWD with paddle shifters.

 

This may (or may not) help:

Actually, looking at it, this pdf only shows older cars, need to find something with more recent information (post 2001)
