I had my 5th gear replaced under warranty and I have I/H/E with a high flow cat. It all depends on how liberal the dealer is whether they give you a hard time, but they cannot denie your warranty claim unless a aftermarket part caused the problem. Plus in my case there is a known problem, and 5th is typically a "non-accelaration" gear. (unless you drive 150mph all the time)
