I'd think it'd be way easier/safer with a manual transmission. Dunno how you go about integrating that with a fully automatic transmission unless a panic stop is done by throwing the throttle to idle and applying the brake (just like any other automatic car). Assumption is that the "idle" setting on the turbine reduces output shaft torque to the point that the clutches on the automatic transmission know what's going on and de-couple the engine from the rear wheels. Pretty big assumption.
