  • Is the transmission part of the engine?

    The first thing to know is what your transmission is. This is the part of the vehicle that connects to the back of the engine offering power from the engine to the wheels.

  • What is the reduction gear?

    Definition of reduction gear. : a combination of gears used to reduce the input speed (as of a marine turbine) to a lower output speed (as of a ship's propeller)
  • What is the meant by gear ratio?

    The gear ratio is the ratio of the number of turns the output shaft makes when the input shaft turns once. A gearset with a 1-inch drive gear and a 2-inch driven gear has a gear ratio of 2:1. Through selection of the proper gear ratio, torque applied to the drive wheels can be multiplied.
B.

What is automatic transmission fluid used for?

  • Is automatic transmission fluid flammable?

    Flammability of automatic transmission fluid was demonstrated in the tests by spraying transmission fluid onto the steel tubing, heated to approximately 1,000°F. The transmission fluid immediately flashed. Both oils ignited easily on the 1,000°F tubing.
  • What type of transmission fluid to use?
