ATX Transmission
Upshifts are lightning-fast and almost immediate. Downshifting is quicker, and while not aggressive, the gear changes come with a satisfying, subtle kick that enhances the sporty feel

Note: Vehicle coding is performed in our facility in Anaheim, CA. Not available for home or remote-based flashing. While this may not trigger flags, BMW can still deny warranty claims if they determine the car is running different software, especially if a fault is software-related.
