You’re not just getting a beefed-up transmission, you're getting the full system—starting with the ATS Five Star torque converter for reliable torque multiplication and fast engagement. The deep ATS transmission pan helps with cooling and fluid capacity, while the included Co-Pilot transmission controller adds intelligence to the shifts, letting you dial in performance as needed. This setup is ideal for high horsepower builds that demand smooth, reliable shifting under extreme conditions. It also retains PTO functionality, making it a solid choice for both work and play. Just keep in mind there’s a $500 shipping surcharge, but for what you're getting, it's well worth the investment if you want peace of mind behind the wheel.
