Enough is enough. 6000 miles on my 04 and I'm starting to get a grind when shifting from 4th to 5th. Did lot's of research and lots of people are having this problem. I now have to put it back to stock and take it to the dealer. It should get fixed no problem. 28 years old. I try not to beat on the car too hard. But the car is ment to be driven fast. and that give me pleasure. Now I jest need a few more mods and I'll beat up on those darn SVT cobras.

 

You might want to try a turbo upgrade before you plan on beating up on some 03-04 Cobras. You might have a chance with a stock one, but how many people leave them stock?
