Replacement transmission oil- a difficult and responsible procedure. The transmission, in general, is considered one of the most complex and important components of a car, and its repair is best left to the professionals. But, if there are no options, you can carry out the mentioned procedure yourself.

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

Breakdowns and oil leaks from automatic transmissions

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

List of functions lubricating fluid Automatic transmission includes:

Thermoregulation. First of all, this concerns the cooling of transmission parts that heat up during driving;
Friction clutch;
Cleaning transmission parts from dust, metal shavings, and other particles that could interfere with the smooth operation of the system;
Protection of parts from corrosion;
Torque transmission. Transmission oil performs this function in a car’s torque converter.

Due to the fact that the oil in an automatic transmission performs important tasks, the “selection” criteria for it are stricter. As a rule, it is recommended to fill with factory oil, which is purchased from official dealers. The same applies to buying a new one. oil filter. Counterfeits of this part are common, and their installation and operation can lead to a catastrophic outcome.

Possible consequences when using low-quality gear oil or failing to replace it in a timely manner:

Increased fuel consumption;
Accelerated wear of automatic gearbox parts;
Rapid engine overheating;
Contamination of the internals of the transmission.

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

Now about the first signs that it is necessary to add or change the lubricant in the automatic transmission:

engine knocking when driving;
Difficulty switching gears;
excessive consumption of gasoline;
deterioration in vehicle controllability.

If any of the above options occur, you should check whether the automatic transmission oil in the Kia Optima needs to be changed.

The process of changing the oil in an automatic transmission

To change the transmission oil in an automatic transmission with Kia Optima, you need to prepare first.

The first stage of preparation is purchase transmission lube and replacement spare parts (primarily this concerns the filter element, which wears out first, and the o-ring drain plug). It is better to purchase them from official dealers so as not to receive a low-quality fake.

The second stage is collecting tools. List necessary tools to change the automatic transmission oil on a Kia Optima:

Set of keys and screwdrivers;
Ratchet (or “star”);
Thick work clothes and, first of all, gloves;
Flashlight or portable lamp;
Puller for filter element;
Funnel;
Rags;
Any large container of 5-7 liters for used transmission oil.

The third stage of preparation - workplace. Ideally, the procedure should be carried out on a lift, overpass or over inspection hole, but, in the absence of these options, you can use jacks.

Having completed the preparation, you can proceed directly to changing the transmission oil in Automatic Kia Optima.

First you need to warm up the car engine. A trip of 8-10 kilometers is enough for this. This is required so that the viscosity level of the oil decreases and it flows out better.

Then the car is installed in the 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 thick work clothes. In addition to gloves, it is recommended to wear a mask and welding (or other similar) goggles to protect your face and head.

A prepared container is placed 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. Usually the grease flows out within 5-10 minutes. It will not be possible to drain all the “working off” at one time. To do this, the procedure must be repeated 3-4 times, using a special pump.

The next step is removing the pallet, for which you need to unscrew all the mounting 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 completely unscrewed.

After removing the tray, it is cleaned, as well as the magnets located on it. The task of the latter is to collect metal shavings that inevitably appear during engine and transmission operation due to friction of parts. The magnets are cleaned with a rag. The tray - with a special cleaning liquid.

Having finished cleaning the pan, you can install a new one. transmission filter. Before installing it, the threads on both the filter and seat wiped with new oil. You can use your hands to twist (if your strength allows), or special key. The main thing is not to damage the valuable part.

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

Finally, you can pour new oil into the automatic transmission through the hole for the dipstick. Cold lubricant will be poured, so the level must be checked at the “COLD” mark. Then the car starts and makes another trip, after which the lubricant level is checked at the “HOT” mark.

When should you change the automatic transmission oil?

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

But operating conditions may 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. There are 4 marks on the dipstick itself, two each for Min and Max. The lower pair is designed for checking the oil level when the engine is cold, the upper pair is used when the engine is warm. Therefore, the check must be done in two stages. The sequence of actions is the same: remove the dipstick, wipe it with a rag, put it back in and take it out again. This is done once when the oil is cold, and once after a short trip.

At the same time, you can check the condition of the oil. Ideally, it should be a light yellow or even light pink shade. Darkening indicates the imminent need to replace it in the Kia Optima automatic transmission. The presence of burning and shavings indicates an urgent need full shift both oil and filter with pan.

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

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

Note: In progress scheduled maintenance Checking the ATF level is usually not necessary. The ATF level should be checked if a leak is detected (after repairs are completed).

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

Turn out ( filler plug) bolt “A” on top of the automatic transmission (when installed, tightening torque of bolt “A”: 34.3~44.1 Nm (3.5~4.5 kgf m, 25.3~32.6 lbf ft), if the bolt becomes loose, be sure to replace its gasket (ring))

2. Pour 770 ml of ATF SP-IV into the filler hole.

3. Start the engine (without pressing the brake and accelerator pedals at the same time).

4. Check the GDS scan tool to ensure that the ATF temperature is between 50~60°C(122~140°F).

5. On Idling Smoothly move the gear lever from position “P” to “D”, then back from “D” to “P”. Repeat this cycle again.

Caution: You must hold in each position for at least 2 seconds.

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

Caution: The vehicle must be level.

7. The ATF level is considered correct if the oil flows out through the bypass hole in a thin, uniform stream. Complete the procedure by tightening the control plug.

Note: How to check the oil level (for excess or deficiency):

a) excess: ATF flows out through the bypass hole in a strong flow;

b) disadvantage: ATF does not flow out.

Caution: If the automatic transmission and ATF cooler are not damaged, and the automatic transmission housing and control valve block are properly tightened, ATF should flow out after completing steps 1-7. If ATF does not flow out after completing operations 1-7, inspect the automatic transmission unit. Replace the gasket each time the ATF level plug is loosened.

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

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

1. Remove the drain plug “A”, completely drain the ATF fluid and tighten the drain plug (When installed, the drain plug tightening torque: 34.3 ~ 44.1 Nm (3.5 ~ 4.5 kgcm, 25.3 ~ 32. 6 lb/ft)).

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

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

Changing the oil in the box Kia gears Optima is most often associated with the repair of the automatic transmission itself, or it is replaced with a new one during work to eliminate oil leaks, since it must be drained to carry out the work. Automatic transmission oil is filled by the manufacturer once for the entire service life of the vehicle. It is recommended to entrust the oil change in the Kia Optima automatic transmission to professionals, but in some cases you can cope with this operation on your own.

Functions ATF oils in automatic transmission Kia Optima:

effective lubrication of rubbing surfaces and mechanisms;
reduction of mechanical load on components;
heat removal;
removal of microparticles formed due to corrosion or wear of parts.

The color of ATF oil for Kia Optima automatic transmission allows you not only to distinguish between types of oil, but also helps to find out in the event 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 oil in the engine is yellowish.

Reasons for oil leakage from automatic transmission in Kia Optima:

wear of automatic transmission seals;
wear of the shaft surfaces, the appearance of a gap between the shaft and the sealing element;
wear of the automatic transmission sealing element and the speedometer drive shaft;
backlash input shaft automatic transmission;
damage to the sealing layer in the connections between automatic transmission parts: pan, automatic transmission housing, crankcase, clutch housing;
loosening the bolts that connect the above automatic transmission parts;

Low oil level in the Kia Optima automatic transmission is the main cause of clutch failure. Due to low fluid pressure, the clutches do not press well against the steel discs and do not contact each other tightly enough. As a result, friction linings in automatic transmissions Kia Optima become very hot, charred and destroyed, significantly contaminating the oil.

Due to a lack of oil or low-quality oil in the Kia Optima automatic transmission:

the plungers and channels of the valve body become clogged with mechanical particles, which leads to a shortage of oil in the bags and provokes wear of the bushing, rubbing parts of the pump, etc.;
overheat and wear out quickly steel wheels gearboxes;
rubber-coated pistons, thrust discs, clutch drum, etc. overheat and burn;
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 suspension, which under high pressure creates a sandblasting effect. Intense impact on the valve body leads to thinning of its walls at the locations of the control valves, which can result in numerous leaks.
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 on hot oil, the lower pair - on cold oil. Using a dipstick it is easy to check the condition of the oil: you need to drop some 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 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 of a “lower class” than the prescribed one.

Synthetic oil for the Kia Optima automatic transmission is called “non-replaceable”; it is filled for the entire life of the car. This oil does not lose its properties when exposed to high temperature and is designed for a very long period of use of the Kia Optima. But we must not forget about the appearance of mechanical suspension as a result of wear of the clutches over a very significant mileage. If the automatic transmission has been operated for some time in conditions of insufficient oil, it is necessary to check the degree of contamination and, if necessary, replace it.

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

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

A partial oil change in a Kia Optima automatic transmission can be done independently. To do this, just unscrew the drain on the pan, drive the car onto an overpass, and collect the oil in a container. Usually up to 25-40% of the volume leaks 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 changes will be required.

A complete Kia Optima automatic transmission oil change is carried out using an automatic transmission oil change unit, car service specialists. In this case you will need more oil ATF, which is what the Kia Optima automatic transmission holds. For flushing, one and a half or double volume of fresh ATF is required. The cost will be more expensive partial replacement, and not every car service provides such a service.
Partial replacement of ATF oil in a Kia Optima automatic transmission according to a simplified scheme:

Unscrew the drain plug and drain the old ATF oil;
We unscrew the automatic transmission pan, which, in addition to the bolts holding it, is treated along the contour with sealant.
We gain access to the automatic transmission filter; it is advisable to change it at every oil change, or rinse it.
At the bottom of the tray there are magnets, which are necessary for collecting metal dust and shavings.
We clean the magnets and wash the tray, wipe it dry.
We install the automatic transmission filter in place.
We install the automatic transmission pan in place, replacing the automatic transmission pan gasket if necessary.
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 when it is cold. After changing the oil in an automatic transmission, it is important to check its level after driving 10-20 km, already with the automatic transmission warmed up. If necessary, top up to level. The regularity of oil changes depends not only on the mileage, but also on the nature of driving the Kia Optima. You should focus not on the recommended mileage, but on the degree of contamination of the oil, systematically checking it.

Kia Optima is quite young and almost every car is serviced by official dealer. But certainly in the future every owner of this car it will be necessary to service your car yourself or at a car service center (although every owner should at least know the volume fuel tank). And for this you need to know the filling volumes and brands of fuels and lubricants recommended by the manufacturer. To help Kia owners Optima table below filling containers And lubricants.
