I am going to purchase the banks git kit. It comes with the monster exhaust and the big hoss programmer. How long do you think a stock transmission will last, I never pull more than 5K and that is once or twice every 2 weeks in the summer the rest of the driving is just city and highway driving. I don't need the extra power for anything but kicks and giggles. I also understand that the banks kit comes with the ability to defuel the truck when the torq conv locks up, which they claim does not hurt the trans. Any info would be appreciated.
