Why this module?
What will you learn?
In the first study section, after presenting the different transmission types, we go through the automatic tranmission’s structure, for example the torque converter, hydraulic system and transmission mechanics in-depth. In this section you will learn what happens inside the transmission when you see the modes P, R, N, D, D1, etc. on the instrument cluster display. In the section “Components”, you will study the torque converter’s operation, which is made easy by the module’s visual animations.
The planetary gear sets and the clutches and brakes used to control them make up their own entity. In the planetary gear set operation you familiarise yourself with gear sets that have made the development of the transmission possible, for example Compound Planetary Gear Sets (Ravigneaux ja Simpson Gear Set) and Nested Planetary Gear Sets.
In the section on hydraulics you learn what kind of different hydraulic pressures are regulated in the transmission, how different torque converters are controlled and what the shifting pressure, that makes shifting smooth, is.
In the second study section, the center is the control system of the mechanics and hydraulics, and its electrical structure. With this module you learn how to utilise the electrical and structure schematics provided by the manufacturer, and use them to make an assumption of what operational checks can be performed with electrical measurements.
The hydraulics control uses different pressure levels, such as; line pressure, shifting pressure, control pressure and torque converter pressure, with which the pressure is kept stable and solenoids’ mechanical movement is quicker even though the control currents are lower.
In addition to the regulating and switching solenoids used in the control, the manual valve (gear selector valve) is a central part of the operation, even though it might be fully electrically operated.
In addition to their compact construction, automatic transmissions are special due to the fact that transmissions contain very different amounts of sensors, which we are used to use as aid when troubleshooting. Many programme and calculation measures decrease the need for sensors. That is why it is crucial to understand the function of the sensors in the transmission, since a fault in these might interrupt driving at once.
At the end of the study section, we get to know the driver’s functions, control devices and driving modes’ differences in the shifting maps. The electrification of the gear selector used by the driver has also brought many versions of its connection to the transmission itself. Electronic use also has a crucial effect on the release of the Park Lock mechanism in a fault situation.
