I just recently bought an 2002 Audi A4 with 126000 miles on it. Stupidly I bought it without getting it checked first.. I took it to a trans shop after feelig a little bit of a pull.. Did the road test hooked it up to the computer and no codes came up. They put it on the lift and undid a plug and said since fluid came out I need a new transmission. Any suggestions or comments on this?
