Advice 1: How to check the automatic transmission

In modern cars set of mechanical, automatic and semi-automatic gearbox. Last are those that have the ability to change mechanical control box to automatic. Motorists know that every car is recommended oil type for transmission. It is therefore very important to know the number of your automatic transmission.

Experts say that all the problems that arise when using the automatic transmission, occur due to improper operation or untimely maintenance which consists in changing the transmission fluid, the diagnosis and repair of faults.
2
To find this number in several ways. On the front cover of the gearbox usually affixed a sticker with a number and information about the automatic transmission. The room is duplicated and on the dipstick for automatic transmission.
3
On the car body in the area of the right support of the engine (to see it, it is sometimes necessary to remove the air filter housing) there is a metal plate inscribed with information about the number of automatic transmission.
4
Another way to determine the number of the automatic transmission is a request to the website of the manufacturer of your car. Every car produced late 1980, has your VIN code (Vehicle Identification Number) – personal identification number. Usually it is indicated in the registration certificate of the car, he also laid in memory of the onboard computer. In addition, the VIN code applied on the windscreen of the car and lower the arch of the driver's door. Sending your VIN number on the manufacturers website, you get a number you are interested in part or automatic transmission.
Note
In recent years, the automotive market becoming more and more popular automatic transmission. Especially in the famous car manufacturers.

Rоробки slots have undeniable advantages. The main one is driver comfort, fuel economy, a more benign operating conditions of the engine and running parts. However, these devices have disadvantages: less than the mechanical boxes, efficiency, limiting the use of an automatic gearbox (the inability to start the car with push, inconvenience, towing rope, etc.), the high cost of repair and maintenance. Therefore, not all Russian motorists choose cars with automatic transmission.

Advice 2: How to adjust automatic transmission

The adjustment process of the automatic transmission is the smoothness of switching low and high transmission. Such adjustment is achieved by reducing or increasing the length of the cable transmission, and throttle position.
How to adjust automatic transmission
Instruction
1
Turn on the ignition and look at the instrument panel. CHEK if the bulb is not lit and shows no faults, then open the hood and check the TPS sensor (throttle position). Lower the set screw, lift the flap up to the stop and release it suddenly. In response, you will hear a click, that says that valve hit the stop. Tighten up the set screw again and click the shutter, try to catch the moment when valve will stop to "snack".
2
Loosen the screws and connect the multimeter to the idle contact (IDL), which is usually on the TPS connector second from the top or bottom. Insert the feeler gauge with a thickness "N" between the stop screw and the throttle. Gently rotate the sensor and make sure that the opening of the valve needle started to move – this is the beginning cutoff idle. Lock the screws.
3
Inspect the engine if there is the bypass adjustment screw idling, then just turn it in that if the other. If the screw is there, the motor has a special regulator, which is located at the bottom of the damper unit. For configuration, tighten up the two screws located on it.
4
Adjust cable of automatic transmission. To do this, check worn to completely cover the rope on the metal thickening. Soft switching is achieved by lengthening the length of the cable, it is necessary to Unscrew one nut and the other on the contrary, spin. To increase the rigidity do the reverse operation of nuts that will reduce length.
5
Check out how it works "kick-down". To do this, enter the speed of 50 km/h and then sharply pedal to the metal. Let's see how to behave in automatic transmission and car in General. If configured correctly, rpm will increase rapidly, the car "sit down" and abruptly jerk forward. Keep the pedal to the gearbox itself has to switch from low gear to higher. If you chose the wrong length of rope, the engine will just gain momentum, and the automatic transmission will be silent.

Advice 3: How to identify model of automatic transmission

Cars with automatic transmission is comfortable to drive and more comfort for city driving. But classical automatic transmission has become exotic to her replaced by new types of transmissions, which has several modes of transmissions, save fuel consumption and offer more control. To determine which model of automatic transmission is installed on a particular machine, you need to know the technical features of these devices.

1
On the cars of the old generation of automatic transmissions used on the principle of classical hydraulics, ie the car is missing wheels, engine, and torque is transmitted by means of two turbines. In modern automatic control is due to the electronics. These boxes have a semi-automatic control with manual. To define such a box, just look at the mode switching. Such automatic transmission may be a sport mode, economy or winter drive. Such models transmission applies Tiptronic, Autostick , Steptronic.
2
More popular now gaining a car with CVT. To verify such model of the transmission just. If the hydraulic switch of speeds, you can monitor the tachometer readings, the CVT works very smoothly, but engine sound it monotonous. On this model the automatic transmission as there is manual control mode.
3
Let's see how behaves your car when you are trying to dramatically pick up speed. If a sharp tap on the gas, the car roars, "think" and then takes a leap – so it's a robotic gearbox. Although conceptually it is closer to "mechanics", automatic control is possible and the transition to manual mode. In manual mode the car behaves adequately with a sharp set of speed. But the fuel consumption of machines "robot" is much lower than the classical "automatic".
4
Look at the vehicle transmission. If it says DSG, you robotic transmission with two clutches. Two clutch disc are responsible for switching the even and odd gears. In General, this box is positioning itself as a sports. She really has a sports mode and possibility of switching to manual control. However, to meet such a box on such a non-sports car like the Skoda Yeti. Although acceleration from a box is really faster, and most importantly softer than the usual "robot".

Advice 4: How to determine a fault automatic

Automatic transmission not among the most reliable devices in the vehicle and therefore requires regular inspection. Finding of fault, the owner of the machine should eliminate them as quickly as possible. Determining the status of the automatic transmission may also be required in the preliminary examination of the car before buying.
How to determine a fault automatic
Instruction
1
Check the quality of the transmission fluid. It should be clean and bright, with no apparent sediment. The precipitate formed is steel and aluminum shavings, can become a symptom of the very poor condition of the automatic transmission. Please note: valid only the presence of very small, small amount of shavings, as it may be in the transmission fluid after running nodes.
2
See if the filter is plastic shavings. Its presence may indicate faulty bearings or gears. As a result, the filter becomes clogged, the flow of fluid is sharply reduced and the automatic transmission fails. The most disturbing symptom is a black oil color and a strong smell of burning coming from it. In this case, most likely, will have to contact the service center for overhaul of the automatic transmission.
3
Calculate the average time shift. The translation from N to R or D the car should respond very quickly. The delay is longer than 1.5 seconds indicates a serious malfunction of the automatic transmission, the elimination of which need to be addressed as early as possible. Do not hesitate to repairs: firstly, if you make it on time, without waiting for the transmission output from the system that it will cost you less, and secondly, in such cases, it may lead to accidents.
4
Pay attention to the process of shifting. It should not be accompanied by extraneous sounds: the rattle noise, a sharp knock, etc. are Also unacceptable vibrations and strong shocks. Note: we are only talking about a very strong, sharp shocks, but not soft and smooth!
5
Rate the change of the rotational speed of the crankshaft. If the gear change is increasing too sharply, disproportionately accelerating means, the automatic transmission needs a thorough diagnosis and repair.
6
If you have doubts about the serviceability of the automatic transmission your vehicle, contact the service center. Experienced mechanics will diagnose and tell you the condition of the automatic transmission and whether to repair or replace.
