Torque converters were invented for the same reason many other automotive features evolved: for convenience. The original transmissions were manual, and clutches and stick shifts worked just fine to shift. However, people soon began craving convenience, and eventually the automatic transmission came into being.
In the 1950s, the automatic transmission became quite popular, and stayed the favorite of drivers all over until the energy crisis of the 1970s. Up until this point, torque converters rarely came with a lockup function, were inefficient, and used more fuel. When gas became scarce, manual transmissions became popular again, until car manufacturers improved and began using lock up torque converters exclusively in their cars. From then on, automatics have ruled the roads.
Automatics with custom torque converters are popular on the drag strip, as well. That’s because the torque converter has the ability to multiply torque from the engine to the wheels, and can propel a car forward faster from a dead stop.
If you’re looking to beef up your street car for use at the track, a high performance torque converter is a good place to start. Contact the automotive experts at Precision Industries to determine which torque converter model is right for your vehicle.
