Automatic transmissions appeared in the second half of the last century, but initially such transmissions had only 2-3 steps, while the driver forcibly could not select the gear in which the engine was running. Only in the nineties did the first automatic transmissions appear, which had additional functions for simulating manual transmission. It is about the features of using such a manual mode with an automatic transmission that and what to do with old license plates ontario we will talk about in this article.
For the first time, the design of automatic transmissions with the possibility of manual control was used by the German company Porsche, in which such automatic transmissions were called Tiptronic. Subsequently, this name stuck, therefore, even today, many such machines with the function of manually changing the speeds are called tiptronics.
The control electronics of such tiptronic boxes monitors various parameters of the engine, including the analysis of the engine speed. If the driver keeps the engine at high revs for too long, then the automation will force the transmission to a higher stage, thereby preventing critical engine breakdowns.
Nevertheless, such a manual mode cannot be called full-fledged, since the automation itself, if the engine is kept at high speeds for a long time, itself decides to activate the top gear. But at the same time, the driver has the opportunity to better realize the engine power, he chooses a specific gear himself, which allows him to feel confident behind the wheel, especially when driving over rough terrain.
Features of gear shifting
Mechanically, the steps on the machine can be switched using the selector, which is shifted to the left in Drive to activate the manual mode, after which, by moving the selector up or down, you can increase or decrease the current gear. Sports cars today also have special paddle shifters on the steering wheel, with which you can change gears, without the need to perform any manipulations with the gearbox selector.
Driving a car
Driving a car with such a tiptronic box does not present any particular difficulty. In fact, all the driver needs to do is start the car, depress the brake pedal, press a special button on the selector that unlocks the box, then activate Drive mode and start driving. Already in motion, the selector can be moved to the left by switching the box to Manual mode.
Usually, after activating such a manual mode, a figure with the current speed of the automatic box lights up on the dashboard in a small display window. Further, by moving the selector up or down, the driver can increase or decrease the steps to better realize the dynamic characteristics of the engine. At the same time, the automation constantly monitors the engine speed indicators and the current speed, which eliminates the motor overload even if the speed is incorrectly selected.
It is often required to manually change gears on an automatic machine when you need to quickly accelerate and quickly overtake. All that the driver needs to do in such a case is to switch the box to manual mode and reduce the speed by one step, which will immediately raise the revs, and the car will start to accelerate sharply and quickly. Usually, as soon as such overtaking is completed, the transmission is returned to Drive mode, after which the revs immediately drop to optimal for a particular speed.
It is also often required to activate the manual mode on the machine in winter, which allows the driver to avoid slipping in deep snow, a knurled track or when starting off on ice. Previously, this on conventional machines was very difficult, and with the advent of tiptronics, driving a car has become much easier.
Let’s sum up
Most automatic transmissions today have a manual mode, which allows the driver to select the gearbox speed at will. Most often, such a manual transmission mode is used when a sharp acceleration is required or when starting in winter from deep snow and on slippery surfaces. At the same time, the automatics monitors all the parameters of the transmission, preventing its failure even if one or another of the steps in the automatic transmission is incorrectly activated.
