Manual automatic transmission Steptronic or Tiptronic

The streets are filled with cars, and the lucky person who owns an automatic car just puts the gear stick on the (D) position and just presses the gas pedal. These brakes automatically as soon as the gas pedal is pressed. As for the owners of normal gear cars, this journey ends with pain in the left foot from too much pressure on the clutch pedal, so that the balance of the gas and clutch feet sometimes gets confused and the car is invalidated on the ride.

So the luxury and comfort with the automatic gearbox is over, but human nature likes to control the timing of the gear shifts and does not like to wait for the automatic gearbox shifts, so I made a lot of sense about this automatic gearbox, especially since the number of its shifts was no more than three or four in the fifties and until recently In addition to the high prices of its parts and the scarcity of the possibility of maintenance. . . . However, in the past few years, the number of automatic gearboxes has increased to five, six and seven, and to saturate the driver in the timing of the shifts, a switch has been placed for him by which he can choose the driving style. As for the sport driving, in which the gear shifts the speed at a higher number of engine laps to achieve the required maneuvering. Or comfortable driving, in which it achieves comfort, quietness, smoothness and fuel economy. . However, this method did not satisfy them.The hydraulic control unit in the automatic gearbox was replaced by an electronic control unit, and the hydraulic valves were replaced with electromagnetic valves to make the response faster and more accurate in control, and the intelligent transmission appeared, which feels the driver’s desire to drive in sporty mode or comfortable mode, with the amount of pressure on the gas pedal, but that did not satisfy who want the initial start fast especially young people and the work of the race with others, even transmission speed automatic manual appeared in 1990 in the automobile Boxer 968 cars Porsche named Baltpetronak ( the Tiptronic ) or Alstpetronak ( Steptronic ) or Altach shaft (Touch Shift) or Wallace Mattek ( S-matic) and these designations are for one type of manual automatic transmission, depending on the car model.

This type of transmission for the automatic gearbox has two modes of transmission, the first is like the normal automatic gearbox by placing the gear stick in the (D) position, and the second method is for the driver to make the shifts himself and according to his desire, just like the normal gearbox, so he gets the power he desires in any At a time he wants, he moves the stick to the manual lane, in which he can click the stick forward towards the (+) sign, moving from the first to the second, then click it to the third and so on to increase the speed and increase the number of laps, or he clicks the stick backwards towards the (-) sign to reduce the car’s speed, and in some cars There are two buttons, one positive and the other negative, on the steering wheel to make it easier to take shifts.The tiptronic, again, is an automatic gearbox designed to use a Torque Converter, and it does not have a normal gearbox or clutch wear, or it is a semi-automatic gearbox, and the tiptronic sometimes makes the shifts automatically while driving if the driver neglects the transmission while he is in manual mode This is to preserve the gearbox and the engine from exceeding the danger stage. If the car was moving quickly and then entered a signal and the car was guided, the gearbox automatically drops the gears so that the engine does not turn off if it turns at a slow speed while it is interlocked at a high speed, then the car stopped at the signal and started the movement after it was opened And you are in the manual mode and are unaware of that gear, in this case it is in the first gear mode. If the car goes and increases the speed until it is about to reach the maximum and you do not transfer to the second, the tiptronic will transfer from the first to the second automatically, as well as it can be transferred from the second to the second. The third also automatically and automaticallyI am still in manual mode, then the gearbox waits for the driver to notice from his negligence to make the rest of the shifts manually from the third to the fourth and then to the fifth. The gear does not make these moves automatically unless you are in the (D) position.

The automatic transmission in tiptronic cars also has two modes of operation, the automatic comfort mode (Comfort) and the sport mode ( Sport ), and through each mode there are additional modes that the driver chooses himself to adapt to the driving requirements required to obtain a quality of transport that the computer prepares to give the imposed driving requirements and affect the way Pressing the gas pedal is to be transferred from sporty mode to comfortable or vice versa automatically. Thus, we are in the sports mode, and we do not forget that pressing the pedal for the last of its journey achieves Kickdown in the required time.
