3.  TRANSMISSION CONTROLLER – Compact plug and play unit pre- programmed to match your driving style. Intelligent computer monitors your throttle and vehicle speed to provide transmission performance that meets your demands – from easy cruise with softer shifts – to tire blazing, spine tingling firm shifts – all in one transmission solution. The best of both worlds – comfort and performance!
