In this article, you will learn how to correctly check the oil level in a six-speed (6 tbsp.) Automatic transmission, as well as how to replace the fluid in the automatic transmission of many Kia models and Hyundai.

Checking the oil level (fluid, ATF) in the 6-speed automatic transmission Kia / Hyundai.

Note: In progress scheduled maintenance an ATF level check is usually not required. The ATF level should be checked in the event of a leak (upon completion of the repair).

Caution: When checking the ATF level, do not introduce dust, foreign substances, etc. through the filler opening.

1. Turn out ( filler plug) bolt “A” on top of automatic transmission (when installed, tightening torque of bolt “A”: 34.3 ~ 44.1 Nm (3.5 ~ 4.5 kgfm, 25.3 ~ 32.6 lbf Ft), if the bolt looses, be sure to replace its gasket (ring))

2. Fill the filler port with 770 ml of ATF SP-IV.

3. Start the engine (do not press the brake and accelerator pedals at the same time).

4. Verify the ATF temperature is 50 ~ 60 ° C (122 ~ 140 ° F) with the GDS diagnostic scanner.

5. On Idling smoothly move the gear lever from “P” to “D”, then back from “D” to “P”. Repeat this cycle one more time.

Caution: Each position must be held for at least 2 seconds.

6. Raise the vehicle and remove the ATF level plug “A” from the control valve cover while the engine is running (when installing, tightening torque of the ATF level plug: 34.3 ~ 44.1 Nm (3.5 ~ 4, 5 kgfm, 25.3 ~ 32.6 lb-ft)).

Caution: Vehicle must be level.

7. The ATF level is correct when the oil flows out through the overflow hole in a thin, uniform flow. Complete the procedure by tightening the check plug.

Note: The way to check the oil level (over or under):

a) surplus: ATF flows out through the overflow hole in a strong flow;

b) disadvantage: ATF does not flow.

Caution: If the automatic transmission and ATF cooler are intact, and the automatic transmission crankcase and the control valve block are tightened normally, ATF should flow out after completing steps 1-7. If after completing operations 1-7 ATF does not flow out, inspect the automatic transmission unit. Replace its gasket after every loosening of the ATF level check plug.

8. Lower the vehicle on a lift and tighten the filler bolt.

1. Unscrew the drain plug “A”, completely drain the ATF and tighten the drain plug (when installing, tightening torque drain plug: 34.3 ~ 44.1 Nm (3.5 ~ 4.5 kgfm, 25.3 ~ 32.6 lb-ft)).

Caution: It is advisable to install a new plug ring (gasket).

2. Fill in approximately 5 liters of ATF SP-IV approved fluid through the top filler bolt.

Replacement transmission oil- a difficult and demanding procedure. The transmission, in general, is considered one of the most difficult and important parts of a car, and it is better to leave it to a professional to repair it. But, if there are no options, you can carry out the mentioned procedure yourself.

This article will discuss how to change the oil in the Kia Optima at home (more precisely, "garage") conditions.

Breakdowns and oil leaks from automatic transmission

First, you need to answer the question: why do you need gear oil?

Feature List lubricating fluid Automatic transmission includes:

• Thermoregulation. This primarily concerns the cooling of transmission parts that heat up during driving;
• Friction clutch;
• Cleaning of transmission parts from dust, metal shavings, and other particles that can interfere with the smooth operation of the system;
• Protection of parts from corrosion;
• Torque transmission. This function is carried out by the transmission oil in the torque converter of the vehicle.

Due to the fact that the oil in the automatic transmission performs important tasks, the selection criteria for it are stricter. As a rule, it is recommended to fill in factory oil, which is purchased from official dealers... The same applies to buying a new oil filter... Counterfeits of this part are common and their installation and use can be disastrous.

Possible consequences when using low-quality transmission oil or if it is untimely changed:

• Increased fuel consumption;
• Accelerated wear of parts of an automatic transmission;
• Rapid overheating of the engine;
• Contamination of the interior of the transmission.

All of the above breakdowns and complications in the operation of vehicle systems are potentially hazardous. Therefore, it is recommended to use only high quality gear lubricant, as well as the filter / sump.

Now for the first signs that it is necessary to top up or change the lubricant in the automatic transmission:

• engine knocking when driving;
• difficult gear shifting;
• overconsumption of gasoline;
• deterioration in vehicle handling.

If any of the above options occur, you should check whether an oil change in the automatic transmission in Kia Optima is required.

The process of changing the oil in an automatic transmission

To change the transmission oil in the automatic transmission on the Kia Optima, you must first prepare.

The first stage of preparation is the purchase of transmission lubricant and spare parts for replacement (first of all, this concerns the filter element, which wears out first, and the sealing ring of the drain plug). It is better to buy them from authorized dealers, so as not to get a low-quality fake.

The second stage is the collection of tools. List necessary tools to change the oil in the automatic transmission on the Kia Optima:

• A set of keys and screwdrivers;
• Ratchet (or "star");
• Thick work clothes and, first of all, gloves;
• Lantern or portable lamp;
• Filter element remover;
• Funnel;
• Rags;
• Any large capacity of 5-7 liters for used gear oil.

The third stage of preparation - workplace... Ideally, the procedure should be carried out on a lift, overpass or over a viewing pit, but if these options are not available, jacks can be used.

After completing the preparation, you can proceed directly to changing the transmission oil in the Kia Optima automatic transmission.

First, you need to warm up the car engine. A trip of 8-10 kilometers is enough for this. This is required to lower the viscosity of the oil and allow it to flow better.

Then the car is installed in a prepared place, the main thing is that the car owner has access to the bottom. Of course, before starting the procedure, you need to change into tight work clothes. In addition to gloves, it is recommended to wear a mask and welding (or similar) goggles to protect your face and head.

A prepared container is installed under the drain plug on the pallet, after which the plug is unscrewed. Then the old oil is drained from the Kia Optima automatic transmission. Typically, the grease will drain out within 5-10 minutes. All the "working off" at one time will not work. To do this, the procedure must be repeated 3-4 times, while using a special pump.

The next step is to remove the pallet, for which you need to unscrew all the fastening bolts, except for the two distant ones. When the pan tilts, all the remaining oil should drain from it, and only then, using a ratchet, can the remaining bolts be unscrewed to the end.

After removing the pallet, it is cleaned, as are the magnets located on it. The task of the latter is to collect metal chips, which inevitably appear during engine and transmission operation, due to friction of parts. The magnets are cleaned with a cloth. The pallet is a special cleaning liquid.

Once the sump has been cleaned, a new transmission filter can be installed. Before installing it, the thread on both the filter and seat wiped with new oil. For twisting, you can use your hands (if forces allow), or a special key. The main thing is not to damage the valuable part.

The next step is to put the pallet in place. To do this, tighten all the bolts, including the hard-to-reach distant ones. But first it is recommended to check the condition of the gasket. If it looks worn out, it is best to replace it with a new one with gear oil. This also applies to the drain plug gasket.

Finally, you can pour new oil into the automatic transmission through the dipstick hole. Cold grease will be poured, therefore, the level should be checked against the "COLD" mark. Then the car starts up and another drive is made, after which the lubricant level is checked at the "HOT" mark.

When do you need to change the oil in the automatic transmission?

According to the recommendations experienced car owners, in conditions Russian roads replacement of transmission oil for Kia Optima should be carried out every 60 thousand kilometers (or every 7-8 months of vehicle operation).

But the operating conditions can be different, so it is better to check the level and condition of the lubricant in the automatic transmission every 15,000-20,000 km.

This is done using a measuring probe. On some models, to get to it, you need to remove the engine protection. On the probe itself there are 4 marks, two Min and Max. The lower pair is designed for checking the oil level for cold, the upper pair is used when the engine is warm. Consequently, the check must be done in two stages. The sequence of actions is the same: remove the dipstick, wipe it with a rag, immerse it back and remove it again. This is done once with cold oil and once after a short ride.

In parallel with this, the condition of the oil can also be checked. Ideally, it should be light yellow or even light pink. Darkening indicates an imminent need to replace it in the Kia Optima automatic transmission. The presence of burning and shavings confirms the urgent need for a complete change of both the oil and the filter with the sump.

Changing the oil in the box Kia gear Optima is most often associated with the repair of the automatic transmission itself, or it is replaced with a new one in the course of work to eliminate oil leaks, since it must be drained for work. The oil in the automatic transmission is poured by the manufacturer once for the entire service life of the car. It is recommended to entrust the oil change in the Kia Optima automatic transmission to professionals, but in some cases you can handle this operation on your own.

Functions ATF oils in automatic transmission Kia Optima:

• effective lubrication of rubbing surfaces and mechanisms;
• reduction of the mechanical load on the units;
• heat removal;
• removal of microparticles resulting from corrosion or wear of parts.

The ATF color of oil for automatic transmission Kia Optima allows not only to distinguish between oils by type, but helps to find out in case of a leak, from which system the fluid escaped. For example, oil in automatic transmission and power steering has a red tint, antifreeze is green, and in the engine it is yellowish. Reasons for oil leakage from automatic transmission in Kia Optima:

• wear of automatic transmission oil seals;
• wear of the surfaces of the shafts, the occurrence of a gap between the shaft and the sealing element;
• wear of the automatic transmission sealing element and the speedometer drive shaft;
• play in the input shaft of the automatic transmission;
• damage to the sealing layer in the joints between automatic transmission parts: pallet, automatic transmission housing, crankcase, clutch housing;
• loosening of the bolts that ensure the connection of the above-mentioned parts of the automatic transmission;

The low oil level in the Kia Optima automatic transmission is the main reason for the failure of the clutches. Due to the low pressure of the fluid, the clutches do not press well against the steel discs and do not contact each other tightly enough. As a result, the friction lining in the automatic transmission Kia Optima become very hot, carbonized and destroyed, significantly contaminating the oil.

Due to lack of oil or poor quality oil in the Kia Optima automatic transmission:

• plungers and channels of the valve body are clogged with mechanical particles, which leads to a shortage of oil in the packages and provokes wear of the sleeve, rubbing pump parts, etc.;
• overheat and wear out quickly steel wheels gear boxes;
• rubberized pistons, thrust discs, clutch drum, etc; overheat and burn out;
• the valve body wears out and becomes unusable.

Contaminated automatic transmission oil cannot fully remove heat and provide high-quality lubricant parts, which leads to various malfunctions of the Kia Optima automatic transmission. Heavily contaminated oil is an abrasive slurry that creates a sandblasting effect under high pressure. An intense impact on the valve body leads to a thinning of its walls at the locations of the control valves, as a result of which numerous leaks may occur.
You can check the oil level in the Kia Optima automatic transmission using a dipstick. The oil dipstick has two pairs of marks - the upper pair Max and Min allows you to determine the level in hot oil, the lower pair - in cold oil. Using the dipstick, it is easy to check the condition of the oil: you need to drip oil onto a clean white cloth.

When choosing a Kia Optima automatic transmission oil for replacement, you should be guided by a simple principle: it is best to use an oil recommended by Kia. Moreover, instead of mineral oil you can fill in semi-synthetic or synthetic, but in no case should you use oil "lower class" from the prescribed one.

Synthetic oil for automatic transmission Kia Optima is called "non-replaceable", it is poured for the entire service life of the car. Such oil does not lose its properties under the influence of high temperature and is designed for a very long service life of the Kia Optima. But we must not forget about the appearance of mechanical suspension as a result of wear of the clutches with a very significant mileage. If the automatic transmission has been operated for some time in conditions of a lack of oil, it is required to check the degree of its contamination and, if necessary, replace it.

Methods for changing the oil in the Kia Optima automatic transmission:

• Partial oil change in box Kia Optima;
• Complete oil change in the Kia Optima box;

A partial oil change in the Kia Optima automatic transmission can be done independently. To do this, it is enough to unscrew the drain on the pallet, driving the car onto the overpass, and collect the oil in a container. Usually up to 25-40% of the volume flows out, the remaining 60-75% remains in the torque converter, that is, in fact, this is an update, not a replacement. To update the oil in the Kia Optima automatic transmission to the maximum in this way, 2-3 replacements are required.

A complete oil change of the automatic transmission Kia Optima is carried out using the installation for changing the oil in the automatic transmission, by specialists in the car service. In this case, more ATF will be required than the Kia Optima automatic transmission can hold. One and a half or double volume of fresh ATF is used for flushing. The cost will be more expensive partial replacement, and not every car service provides such a service.
Partial ATF oil change in the Kia Optima automatic transmission box according to the simplified scheme:

1. Unscrew the drain plug, drain the old ATF oil;
2. We unscrew the automatic transmission pan, which, in addition to the bolts holding it, is processed along the contour with a sealant.
3. We get access to the automatic transmission filter, it is advisable to change it with each oil change, or rinse it.
4. At the bottom of the pallet there are magnets that are necessary for collecting metal dust and shavings.
5. We clean the magnets and rinse the pan, wipe dry.
6. Install the automatic transmission filter in place.
7. We install the automatic transmission pan in place, replacing the automatic transmission pan gasket if necessary.
8. We tighten the drain plug, replacing the drain plug gasket for the automatic transmission.

We fill the oil through the technological filler hole (where the automatic transmission dipstick is located), using the dipstick we control the oil level in the automatic transmission to a cold one. After changing the oil in the automatic transmission, it is important to check its level after driving 10-20 km, already with the automatic transmission warmed up. Top up if necessary. The regularity of oil changes depends not only on the mileage, but also on the nature of the ride on the Kia Optima. You should be guided not by the recommended mileage, but by the degree of contamination of the oil, systematically checking it.
