In an automatic transmission, however, the gears are never physically moved and are always [...]

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 [...]
