Thanks for the reply...I just picked up an S4, and wanted to know what things to look out for tranny-wise!
Basically if you don't miss a shift you will be fine. Short throws IMO make it easier to miss a shift due to the sloppy linkage on these cars. Other than that you can beat the crap out of them. I have already snapped an axle going after 11 second passes and the tranny was all good.
