Recently, automatic transmissions have become more and more popular. It is understandable, with such a checkpoint, driving a car is much more comfortable. However, the automatic transmission also has disadvantages. Let's figure it out!
1. The control
Modern "automatic machines" as well as "robots" with double clutch can be quite agile in their actions. But this is on rather expensive cars. In general, it should be noted that today's material is more about budget cars. After all, there are almost no versions with manual transmission on premium cars. "Automatic machines" on budget cars are not so advanced. This means that those who like fast active driving will not be able to get full control over the car. For example, when driving quickly through bends, the automatic transmission may suddenly change to an upshift due to which the value of torque on the driving wheels will decrease, and the car may even lose controllability. Therefore, lovers of active driving when buying a budget car, it is better to choose the traditional "mechanics".
2. Weight
Any "automatic" weighs much heavier than a mechanical gearbox. This affects fuel consumption and vehicle handling.
3. Start "from the pusher"
If a car with a manual transmission does not start, then it can be started "from the pusher" by turning the engine through the transmission. There is no such possibility with the “automatic machine”.
By the way, a car with an automatic machine in case of breakdown and towing is undesirable. This can only be done over short distances at speeds up to 30 km / h or with partial loading of the drive wheels.
4. Consumption
And by the way about the expense. The most modern designs of automatic transmissions are close to the “mechanics” in terms of efficiency, but nevertheless the consumption indicators are still leaning in favor of “mechanical” machines.

5. Efficiency
In automatic transmissions of traditional design and "variators", the transmission of torque is not implemented in the most efficient way. In the "machine", it is transmitted through a special device - a torque converter. It consists of two turbine wheels, the space between which is filled with liquid. She transmits the moment. In the "variator" it is transmitted using a V-belt transmission. These devices are much less efficient than the "hard" transmission of traditional "mechanics".

6. Complexity and high cost
Automatic transmission has a much more complex design than "mechanics". Because of this, it is more difficult and more expensive to repair it. And we do not have many good specialists in the repair of automatic transmissions.
Above, we have already said that cars with automatic transmission consume more fuel than cars with a manual gearbox. How can you shorten it? This will help you Moderate fuel consumption tips that don't really work
