TRANSMISSION

A device (full of gears) that uses gearing or torque conversion to effect a change in the ratio between engine rpm and driving wheel rpm. When engine rpm goes up in relation to wheel rpm, more torque but less speed is produced. A reduction in engine rpm in relation to wheel rpm produces a higher road speed but delivers less torque to the driving wheels. Also see auxiliary transmission , automatic transmission , five-speed transmission , infinitely variable transmission , manual transmission , progressive transmission , standard transmission , and synchromesh transmission .
