The ATS' standard transmission is a no-nonsense unit with automatic Touring, Sport and Snow modes. You can shift manually by moving the gloriously conventional gear selector to the left and then pushing it forward and back. (Magnesium steering-wheel shift paddles come only on the Performance and Premium trim levels.) The transmission is more responsive than the CTS automatic, which I've criticized for excessive lag. It upshifts smoothly and doesn't dally when you call for passing power.
