The modern automatic transmission consists of many components and systems that are designed to work together in a symphony of clever mechanical, hydraulic and electrical technology that has evolved over the years into what many mechanically inclined individuals consider to be an art form.  We try to use simple, generic explanations where possible to describe [...]

The transmission is a device that is connected to the back of the engine and sends the power from the engine to the drive wheels.  An automobile engine runs at its best at a certain RPM (Revolutions Per Minute) range and it is the transmission’s job to make sure that the power is delivered to [...]

What important to car speed is moment of inertia. Since automotive use circular shapes for lots of engine parts. Therefore angular momentum is vital element. Moment of inertia, with respect to rotation, is called angular momentum. Angular momentum is the force that has to be overcome to spin a circular component (e.g., a flywheel and [...]
