How to check the oil level in automatic transmission

In a normal automatic transmission oil level will be his position on the dipstick hydraulic system between labels ADD and FULL, when heated with engine oil temperature 66 - 93 C. For a given temperature can be reached by car from 19 to 20 km. Learn more about how to check the oil level in automatic transmission, see this article. Note: If a longer run with great speed, and if the ambient temperature is high, then to obtain the correct result for the oil level in automatic transmissions is necessary to measure only after 30-40 minutes after the engine stops running, as the oil in the gearbox to cool . Check oil level in a Box - automaton can not only at the working temperature, but also at room temperature. If after measuring the oil level is required to lift it, then pouring the liquid should try to avoid overflow of the system, since excessive oil in the box - the automatic is the cause of foaming, and it is squeezed out through the breather. Car with the engine running at idle is placed on a flat plane down the brake pedal. Then the driver, still holding his foot on the brake, in turn, translates lever on all the provisions to ensure the filling of the system box - machine oil. Without releasing the brake pedal, you must move fast lever to the "parking lot" P, or (on some models) to the neutral position N. Then, take your foot off the brake, you must remove the dipstick the oil level automatic transmission, and taking with him the whole preparation, wiping it dry, put back into the filler neck. Next you should re-extract the dipstick and make sure the oil level is, as expected, in the middle of labels ADD and FULL. If the level reaches the lower mark, it is necessary to again pour oil into the filler neck, each time after repeating the above steps. At the end should be back to check the level. After all the action to bring oil level to normal, it is necessary to insert the dipstick back into the filler neck, tightly and completely down to water and dirt gets inside the box - gun. Check the oil level at room temperature, all activities are conducted in the same sequence, but at the same final level should be at the mark ADD. It should be noted that the majority of test leads are one or two labels to determine the level of cold butter (usually in the form of holes or dimples), in some they are presented in the form of the inscriptions: HOT - the oil level is at normal operating temperature, and COLD - level cold butter at room temperature. Attention! Do not forget that the level of cold butter in warming up to normal operating temperature up to 0,6-0,7 see why, if you want to raise the level of oil in the box - machine to the optimum, be careful when dolivanii and prevent overflow. Here are some of the consequences of excessive oil in the box - gun. At a crowded system of automatic transmission oil, butter churning occurs due to the fact that the internal moving parts of the gearbox rotate at high speed. Such oil can not adequately compress the leading and trailing wheels in packages clutch each other, due to the fact that it contains an excessive amount of air. All this leads to slippage of these discs and their combustion, and consequently, the box - machine breaks down. Something similar is happening in the brake system of the vehicle if the air gets there. If excessive oil in the box - manual, it is, frothed, flows out through the breather. Automatic transmission may fail due to excessive air in the oil, as well as at a low level it. If it is not enough in the hydraulic system of the gearbox, the oil pump pumps oil with air. Due to lack of oil pressure on clutch discs, they are, as in the case of the overflow of oil, did not fully adhere and burned. Determining the status of the box - machine on the external signs of transmission oil. Transmission oil or fluid - ATF of automatic transmission fluid (English), carries out one function in a box - manual, but several: by means of oil pressure is created which includes servos, Pincher brake bands, the trailing and leading packaged clutch discs are compressed among themselves that, in general, allows you to switch to a different box - automatic; torque transmitted through the liquid from the impeller of the torque converter which is connected to the engine to the input shaft of the box - machine through the turbine wheel, lubricate moving parts of automatic transmissions, transfers heat of transmissions released by his work. Most popular brands of transmission fluid today - it's DEXRON II, DEXRON III. On the transmission fluid other manufacturers typically indicate that they are produced by the standards of DEXRON. These external characteristics of the transmission fluid, such as color and smell, too, can tell a lot about the state of automatic transmission. If liquid has shades of red, then the gear box in good condition, but black or brown liquid, which then has the smell of burning, says that the box - a machine has a fault. But keep in mind that after the engine starts at the beginning of the gearbox, liquid brown-greenish color with an unpleasant odor, but did not burn, does not indicate a malfunction. It is normal for the box - gun. If the transmission fluid to light brown and small black particles, it is said that the destroyed layer friction brake bands, bearings, clutches, gears. These particles can be detected by measuring the dipstick. If you hit the same water or antifreeze in Auto, the liquid is white and pink. If you identify these signs, you want to remove the oil pan and transmission good look for him to identify any sediment and particles. If you notice all of this in the oil, automatic transmission must be immediately removed, disassembled and cleaned. If there are problems, it is recommended to repair a mandatory flushing the entire cooling system gearbox.
