Automatic transmission with manual shift mode
Introduction
The manual transmission combines the convenience of an automatic transmission with the ability to manually control the gears. This type of transmission allows the driver to select gears manually, like a manual transmission, but without the need to use a clutch.
Operating principle
The manual transmission uses the same components as a conventional automatic transmission, such as the torque converter and planetary gear. However, it also has a built-in control unit that is responsible for manual gear shifting.
Modes
A manual transmission typically has two main modes:
* Automatic mode: The transmission automatically selects gears based on driving conditions.
*Manual Shift Mode: The driver can manually shift gears using the gear lever or steering wheel paddles.
Advantage
The main advantage of a manual transmission is greater control over the vehicle. Drivers can select gears to suit driving style, road conditions, fuel economy or performance.
How to use manual shift mode
To use manual switching mode:
1. Move the gear lever to the manual shift position (usually «M»).
2. To upshift, use the “up” gear shift lever or the “+” steering column switch.
3. To downshift, use the gear shift lever «down» or the steering column switch «-«.
Restrictions
Although manual shift transmissions offer greater control, they also have some limitations:
* Lack of Clutch: Since the gearbox does not have a clutch, the driver cannot fully control the movement of the vehicle.
* Possibility of Damage: If used incorrectly, the transmission may be damaged.
* Increased fuel consumption: In manual mode, it may be difficult for the driver to optimize fuel consumption.
Application
Manual shift transmissions are often used in sports cars, luxury cars and four-wheel drive vehicles. They provide a compromise between comfort and control, making them a popular choice for drivers looking for enhanced driving performance.
