Bring back the original, crisp shifting performance of your vehicle with the MADNESS Autoflash TCU Tuning Tool. Over time, your transmission adapts to different driving styles, potentially leading to slower, less responsive shifts. The Autoflash resets your transmission's shift logic to its original factory state, ensuring smoother, faster, and more precise gear changes—just like when your vehicle was brand new.
Why Choose MADNESS Autoflash?
Modern vehicles feature adaptive transmission learning, which means they adjust shift points and behavior based on driving history. This can result in dull, sluggish shifts, especially if the car has been driven conservatively in the past. The MADNESS Autoflash restores your TCU’s settings to their original factory performance, making your gear shifts feel sharper and more engaging.
