Today's automatic transmission is one of the most complex and interesting parts in cars, and to explain this advanced technology, we need to divide it into four parts.
1- Mechanical 2- Hydraulic 3- Electrical 4- Computer
These four parts in an automatic transmission work in special coordination with each other, making the transmission work and driving more comfortable and enjoyable. Until one of these parts has a problem that causes it to not work properly, that's when you notice the faults and problems in your transmission or car. The turbine in automatic transmissions and the clutch in manual transmissions both do the same job, but they are completely different in terms of how they work, and it must be said that the operation and techn ..........

The location and shape of the gear lever in cars with automatic transmissions can vary, but in general there are three possible modes. A typical automatic gear lever is in the middle of the console, a rotating circle with buttons and lights, or behind the steering wheel similar to a steering wheel. But the function of all of them is the same according to the P-R-N-D concepts. For example, in a typical gear lever, you have to move the gear lever to enter park mode, but in a Mercedes-Benz with a gear lever behind the steering wheel, the park mode is a button on the gear lever. ..........

The transmission oil and its filter must be changed at certain times. In the transmission service, just changing the oil is not enough, and the transmission case must be opened and the filter must be changed or washed, (some filters, especially the wire type, are washable). Taking care of the filter is very important. Because a clogged filter causes less oil flow and severe damage, and often causes the transmission to burn out. Some of the top models of modern transmissions, such as Peugeot 206, Hyundai, Kia, have the filter installed inside the transmission, or in other words, they are disposable transmissions because the life of the transmission ends when the filter becomes dirty and clogged. Therefore, the accuracy of changing the oil on time in these transmissions can practically exte ..........

Most modern cars warn the driver when there is a problem with the automatic transmission or when the transmission fluid needs to be checked by turning on the check transmission light in red or yellow, however, some other cars use other methods to warn about this. The most frequently asked questions in phone calls or in-person visits to us are related to the symptoms that drivers suddenly receive. In this section, we have tried to explain these warning signs in various cars with automatic transmissions.
All modern cars (1995 and up) are controlled by computers. The automatic transmission computer performs two tasks:
1 - Starting the transmission and receiving information from the engine, transmission, ABS, and through this information, it performs commands to perform transmission ..........
