I have an 04' 350 Roadster. After the firse month the tranny started to become harder and felt as if it was grinding into thrid gear. Last year i took it to the dealership with 1500 miles and they told me that they couldnt do anything about it.. How can i get the dealership to replace my tranny, or does anyone know the reason for this prob............
