There
are two types
of
automatic transmission:
• Semi
automatic
• Fully
automatic
Semi Automatic:
• In this type the clutch is operated
automatically, the driver still has to select the gears
Fully Automatic:
• In this type even the gears are
changed automatically by a control mechanism which is
actuated by the
accelerator pedal only. There are only two pedals i.e. For braking and for
accelerating
• An automatic transmission unit does
not require drivers intervention while driving
• A cluster of sensors embedded
within the system constantly monitor the throttle
(acceleration / Deceleration)
input and then optimize (change) the engine response
accordingly
• The driver only uses the
acceleration and break pedals, and can comfortably enjoy the
drive without
having to change gears
• The gear shift moves up
automatically at the optimum shifting level when the driver
presses the
accelerator and the reverse action can be achieved when the break pedal is
pressed
• Automatic transmission is new
concept in India, even though it has been in use for over
four decades in the
U.S. There were only one or two imported models in India that came
with the option of an automatic
transmission
• Cars with automatic transmission
are different from cars with manual transmission in terms
of power,
acceleration, fuel economy and driving comfort
