Performance levels
Heavy duty is for towing, off-road vehicles, campers, motor homes and RVs, trailers, and vehicles that do a lot of stopping and going, such as taxis and law enforcement. Street and strip gives firm, positive, instant shifts while keeping full automatic operation and standard shift points with the selector in Drive. Full competition is for all-out competition racing, with maximum shift feel and control.
Stage 4 delivers full manual control, shifting manually at any RPM. The kit gives positive shifts, keeps the passing gear, has adjustable shift points and includes separator plates.
