AUTOMATIC TRANSMISSION - DRIVE(D)





This position allows the transmission to engage the full range of available forward gear trains, 


allows the vehicle to move forward and accelerate through its range of gears. 


The number of gear ratios a transmission has depends on the model, but they initially ranged from three (predominant before the 1990s), to four and five speeds (losing popularity to six-speed autos, though still favored by Chrysler and Honda/Acura)


Six-speed automatic transmissions are now probably the most common offering Toyota Camry V6 models, the Chevrolet Malibu LTZ, CorvetteGM trucks, Pontiac G8, Ford Falcon BF 2005-2007 and Falcon FG 2008 - current in Australia with 6 speed ZF, and most newer model Ford/Lincoln/Mercury vehicles).


seven-speed autos are becoming available (found in Mercedes 7G gearbox, InfinitiVW Group DSG, as are eight-speed autos in the newer models of LexusBMW ZF 8HP and VW, cars (VW Touareg).
