    Automatic transmission identification are generally identified by their pan shape.The THM200 and the THM250 have pans shaped like a THM350, however, the THM200 will have the words HYDRAMATIC DIV. and METRIC stamped into the pan.An automatic transmission (also called automatic gearbox) is a type of motor vehicletransmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.Some machines with limited speed ranges or fixed engine speeds, such as some forklifts and lawn mowers, only use a torque converter to provide a variable gearing of the engine to the wheels.Automatic transmissions are of three types. The first type is based on a hydro transformer and planet gear, and the second type has a chained mechanic variation device with planet gear, for expensive cars like Audi, but also for cheap cars. The third type is special and it is equipped with double coupler and cylindrical gear provided by BMW or Mercedes. Automatic transmissions are characterized by a high degree of comfort and speed level changes without interrupting power flow. Automatic transmission is cheap, and it meets all the pollution standards. It is comfortable and environmentally friendly.
