TransGo automatic transmission reprogramming kits are designed with performance in mind. Most, but not all models contain additional features like Gear Command that allows you to hold manual low to any speed, and shift back to low at any speed. They are great for strip cars or 4x4 rock crawlers needing to select low and not have it upshift. Most TransGo automatic transmission reprogramming kits can be tuned for HD (Heavy Duty) use by following the recommendations in the kits.
