Reason for contacting us: On a hot Kia Spectra does not go back. When rebooting, reverse gear appeared. With a sharp press on the gas, nothing happened, then a blow and the car starts to go back. Sometimes the drive was lost on a hot car. On a cold one - everything is fine.
The car owner changed the oil in the automatic transmission, but this did not eliminate the malfunction.
Troubleshooting automatic transmission Kia Spectra
- The reverse package is burnt out. This is the standard “disease” of this box.
- Burnt out package of 1st gear (forward).
- There are metal seizures on the automatic transmission oil pump. Precisely from metal, not from friction dust.
- The intermediate shaft needle bearing is scattered.
- The valve body must be disassembled and cleaned.

4-speed automatic transmission F4A-EL (Kia - 4EAT-F, F4E-AT ) developed by Mazda engineers in cooperation with Jatco in 1989 for front-wheel drive cars with an engine of approx. 1.6 liters. It was intended to replace the automatic transmission 3-speed F3A and was installed on Mazda 323, Ford Escorts (list - below). Structurally related to older brother 4EAT-G.
In the early years, childhood illnesses appeared, solving which, the designers changed the hydraulic plate, introduced a new solenoid instead of the kick-down cable, replaced some washers and bearings, and for Mazda Protege, as well as for Fords, since 1998, valve bodies began to be produced in a different modification.
Kia in 1997 chose the valve body modification F4A-EL options for the Mazda 323.
Most often, automatic transmission F4A-EL is found in our repairs as 4EAT-F with cars Kia Rio and Spectra.
Since the beginning of the new century, this rather successful (by the ratio of comfort and price) Ford replaced the transmission with the equally successful (simple and maintainable) 4F27E.
- With a deep pan and a suction tube (for our rare AWD SUVs) No. 244010A.
- And a filter without an oil suction tube (the most popular) with a shallow pan (244010) on right... By design, the filter has a metal mesh, coarse cleaning.
It is recommended to install a fine filter - 100019 in the oil cooling line (ATF) on a repaired age box, in which the nodes have borderline wear.

Typical diseases of automatic transmission F4A-EL
This fairly simple and reliable automatic transmission comes for overhaul with the repair of the torque converter (244001) and the usual replacements of consumables:
- Repair kit for gaskets and oil seals (No. 244002).
Repair kits are almost always ordered from ATOK - a budgetary and fairly high-quality option. Less commonly, the more expensive Precision.
Quite often, for a complete bulkhead of the machine, a maximum repair kit is ordered - Masterkit - 244007. It always requires at least a torque converter bushing, brake band (below) and filter 244010.
The Reverse package burns according to the craftsmen due to worn out rear cover and pump seals, bushing and caliper washer rings. And it leads to the combustion of not only clutches - 244110, but also steel discs - 244130. Even the stubborn steel disc Reverse - 244150 burns with them.
But the price a complete set of clutches (244003) is almost the same as the clutches of these three packages separately, so the craftsmen often order the entire set of clutches.
The entire set of steel rims (244004) is changed less frequently. And they differ in the thickness of the discs in the “3-4” package (1.6mm and 3.3mm) for different cars.
With the age of the box, you have to change the Set of bushings - 244030.
The first to wear out is the converter hub bushing - 244031. Its early wear is associated with the abnormal operation of an undeservedly forgotten torque converter. Maintenance of the torque converter is also included in the list of mandatory overhaul works - 244001.
A consumable in F4A-EL (Kia) is a loaded brake band, (2-4 Band):
- No. 244026. It always changes when the oil is burnt.
Pump gasket - 244310. Solenoids are often ordered with them, when the bulkhead with cleaning the valve body did not solve all the problems.
- Linear pressure solenoid valve EPC (No. 244431)
Often they order outdated SHIFT solenoids, speeds: 2-3 and 3-4. No. 244422. The nominal resistance of these unpretentious shift solenoids is from 13 to 27 ohms. When the resistance of the upper threshold is exceeded, their work causes big problems for the operation of the clutches and iron of the corresponding packages.
Due to abnormal operation of the solenoid EPC (in cars since 1997) in the clutch (and braking) packages, a lack of pressure in the line is formed, which leads to slippage and overheating of the clutches in one of the packages and, as a result, to the burning of the packages, including all the thrust discs and the clutch basket itself (drum) ... The EPC solenoid for KIA machines differs from the American one - 244431.
In older cars with long-term operation with "eaten" bagel and vibrations, you have to change the Converter Reactor, # 244529A (31 Splines) (EAT 43A).
- The planetary row from dirty oil, hard life develops its resource - 244584.
- Together with burnt out clutches, steel and thrust discs on older machines, the clutch drum itself is also changed , Reverse & Forward Clutch Drum (only for Ford / Mazda) - No. 244556 (BU, on right )
or - Clutch drum 3 -4 Clutch No. 244550.
Slightly less frequently changed - Clutch drum 2-4 Clutch EAT 38A (with sun gear) No. 244558. (BOO) on right
Working in dirty oil and vibrations associated with bushing wear affects the oil pump itself.
Often the back cover is replaced (a weak alloy from Mazda).
Usually, due to the lack of original iron for F4A-EL, they buy BU Pump cover No. 422510. left.
The valve body was modified in 1997 by adding another solenoid to it. For Ford and Mazda they released their own modification of the valve plate, and for Kia - their own. Not interchangeable.
Hydraulic plates have a characteristic difference: for Kia - there is a 3-2 valve, for Ford and Mazda - it is not.The new valve body design is very reliable and free from many “childhood diseases” of the first series.
If you notice the appearance of a burning smell in the oil in time and clean the valve body with the replacement of the exhausted solenoid EPC (or SHIFT - Ford / Mazda), 2-3 and 3-4.), then this box runs for a long time and without any problems.

Automatic transmission repair F4A-EL almost always associated with the age of the car and high mileage.
The South Korean concern Kia is one of the ten largest world car manufacturers, occupying an honorable seventh place. In 1999, merging with Hyundai Motor, it becomes its integral partner and is part of the Hyundai Kia Automotive Group. Reliability, durability and reasonable price guarantee the popularity of Kia vehicles.
One of the most popular models is recognized by the Kia Spectra, produced by the concern from 2000 to 2009. In addition to other technical characteristics, the design of the Kia Spectra automatic transmission was especially successful. Gearboxes were developed and assembled by several companies: Japanese Jatco and Mitsubishi, South Korean Hyundai.
During the existence of the model, four modifications of boxes were installed on it.
gears that are similar to each other, differing in minor changes for the purpose of modernization:
- 2000-2004, automatic transmission, modification F4A-EL;
- 2000-2004, automatic transmission, modification A4AF3;
- 2004-2009, automatic transmission, modification F4A42;
- 2006-2009, automatic transmission, modification A4CF2.
The gearboxes are similar, equipped with a control system that can be adjusted to the operating conditions, this allows the characteristics of the shift mode to be optimal, regardless of the driving style. Gearbox layout, planetary with clutch braking. The connection to the engine crankshaft is provided through a torque converter. Four-speed gearboxes, compact, can be used on small cars. Achievement of this size allowed the introduction of a reduced hydraulic unit and special clutches into the design. Reliability and durability are due to the simplicity of the design, but these characteristics are achieved with proper care: high-quality oil in the box, its timely replacement, operation without overheating.
Comparing gearboxes with each other, F4A-EL and A4AF3 differ in installed main pairs with different numbers. The F4A42 box, in comparison with other modifications of the series, can switch to manual mode from drive mode, at which point the driver decides to use the upshift. Thus, maximum torque is enforced, and the electronics monitors and corrects user behavior. As the speed decreases, the transmission itself downshifts. A complete stop forces the automatics to switch to first gear. The gearbox of the A4CF2 modification is distinguished by the presence of a sport mode, at the same time, there is no manual control of the unit.
The decoding of the designations gives the first idea of the product. Products with markings starting with the letter "F" correspond to the classification developed by Mitsubishi, the rest are designed by Hyundai.
- F - the gearbox is designed for front-wheel drive vehicles;
- 4 - an automatic transmission with four gears;
- A - automatic transmission;
- E - electronic transmission control;
- L - the gearbox has a torque converter lock-up function (Lock-Up);
- K - manufactured by Kia Motors Corporation under license from Mazda;
- "42", "51" ... - the stage that the gearbox transfers to achieve maximum torque
- Torque converter.It is used to transfer torque from the motor to the box, it acts as a clutch.
- Planetary row, changes the transmission ratio.
- Band brake, travel clutch (forward, reverse), changes gears.
- The control unit converts vehicle parameters into special signals. The gear ratios in the box are changed taking into account the received signals.
- Oil pump and cooling radiator. Thanks to the pump, a working fluid is present in the torque converter, the radiator maintains its correct temperature.
Important! Heavy use can cause the transmission to heat up to engine temperature or higher. The use of special cooling prevents this. Cooling is provided by blowing an air flow to the radiator, which is built into the engine cooling system, or separately.
Basically, the problems of automatic transmissions are associated with untimely maintenance and the use of low-quality consumables, the first symptoms appear when a mileage of 100,000 km is reached.
- Slipping of the gearbox clutch;
- The instrument panel signals a breakdown in the gearbox mechanism;
- Periodic vibration in the gearbox;
- Gear shifting is accompanied by jerks;
- It turns on poorly, the 4th gear periodically disappears;
- Feeling of shock when shifting gears;
- The transmission makes a lot of noise, slows down.
The appearance of one of the above signs is an excuse to call in to diagnose the box in order to identify and eliminate the cause of the malfunction.
Any box sooner or later fails, when this happens, you need to contact a service station for help. The repair of the Kia Spectra automatic transmission is complicated by the complexity of the correct diagnosis of the breakdown, it is important to correctly analyze what errors the diagnostic stand gives. Correct interpretation of indications, guarantee of minimal problems during repairs.
Failure of the solenoids of the hydraulic block of the gearbox, change as a set;
Solenoid wiring defects, especially in Kia Spectra manufactured before 2007;
Development of the pressure control valve channel, increasing its cross-section;
Leaking pump seals, shaft vibration;
Contamination of the channels in the hydraulic plate, as a result, early combustion of the clutches;
Failure of drums, bushings, differential, bearing.
Parts and mechanisms that are out of order cannot be repaired and are replaced with new parts as a set.
Repair of an automatic transmission is a complex process that requires certain skills and abilities. Its high-quality implementation is due to the use of special devices and installations, which are not available at all specialized stations, not to mention handicraft services.
- The interest of the station in further cooperation;
- Providing a guarantee for work;
- Cleanliness and order in the room, on the territory, in the workshops;
- Ability to control the progress of work;
- Famous station, availability of recommendations.
Due to the complexity of the automatic transmission mechanism, not every station will undertake to repair it. The gearmatic company is popular in our region. High-quality, reliable service and repair of automatic transmissions allowed the company to gain the trust and credibility of its customers.
Car manufacturer Kia is the second largest in South Korea and the seventh in the world. Part of the Hyundai concern. The brand is quite recently present on the territory of Russia and Sochi, but quickly found demand for its cars and firmly established itself in the market. Cars from Kia are cheap, of high quality and correspond to all modern concepts of how a car should look and behave. The automatic transmission for Kia is produced by the Japanese company Jatco; there are also Hyundai transmissions developed in partnership with the Japanese manufacturer Mitsubishi. Kia transmissions are quite reliable and durable, but demanding on oil quality and sensitive to overheating.Repair of automatic transmission Kia in Russia and Sochi is quite well mastered and will not cause trouble.
Kia Sid cars were equipped with a four-speed modern automatic transmission A4CF1. These automatic transmissions are manufactured by Hyundai and are designed for small front-wheel drive cars with engine volumes up to two liters. The boxes from Hyundai are in many ways similar to their Japanese "teacher" Mitsubishi, but along with them the Hyundai automatic transmissions have outgrown the "teachers" a lot and they have many good and high-quality developments of their own.
The design of this automatic transmission is based on the Japanese F4A42 for budget cars. Initially, she had a number of "childhood diseases", which were corrected in the second modification. The latest generations of these automatic transmissions are quite reliable and their service life is comparable to the service life of the Kia Sid car. The lifespan of the Kia Sid box is about 200,000 kilometers in Sochi.
The first moments of servicing a Kia Sid automatic transmission usually include changing the oil and filters. The Kia Sid filter is disposable, it changes when the oil is changed or any repairs.
Repair kits for the Kia Sid automatic transmission are rarely ordered yet - the boxes are quite new and did not have time to leave more than 200,000 kilometers for most owners, and they just save. The clutches, as elsewhere, change only as a set.
The main weak point of this automatic transmission is in the valve body and solenoids. They are unnecessarily loaded and their resource is small. The line pressure solenoids and the pressure regulator are the first to fail. Solenoids are used cheaply, do not like dirty oil and work no more than seven years.
The solenoid valve or its wiring often breaks. It's easier to replace the solenoids with a set and forget about them for another five years. Poor wiring can also be the subject of increased attention. Any valve body, especially on modern automatic transmissions, does not like overheating and dirty oil. The problem of overheating is relevant for warm regions of Russia, for example, in Sochi.
If the pump is operated with a leaking stuffing box for a long time, it is likely to fail. Forced blocking of the torque converter, poor cooling system of the automatic transmission, setting the electronic control unit to squeeze out all the power of their box does not greatly extend its life. The oil gets dirty very quickly from which all the insides of the box suffer and breakdowns occur.

Kia Spectra cars were equipped with a four-speed automatic transmission A4Af-3, produced by Hyundai. The automatic transmission was developed in 2000 for front-wheel drive middle-class cars (according to Korean manufacturers) with engines up to two liters. The design of the Kia Spectra automatic transmission is a modified Japanese development from Mitsubishi called F4A32.
The main repair kits for the Kia Spectra transmission can be ordered non-original, they are cheaper and of acceptable quality.
The Kia Spectra automatic transmission filter is disposable, closed felt, cannot be washed. The brake band in the Kia Spectra automatic transmission is a consumable and changes at every opportunity. The clutches of the Kia Spectra automatic transmission can only be changed as a set. Most often, the clutch packs responsible for moving forward are lit on the Kia Spectra automatic transmission. Most often, the clutch packs responsible for moving forward are lit on the Kia Spectra automatic transmission. In the wake of them, if not changed, drums may fail, bushings turn, oil starvation begins and the rest of the Kia Spectra automatic transmission mechanisms burn out.
The pump bushing, and the entire set of bushings, often fails on the Kia Spectra automatic transmission and is changed as a set.
A4Af-3 automatic transmission for Kia Spectra
The stator or drum can be damaged in the pump. If the driver did not notice the breakdown, then the Kia Spectra automatic transmission will travel some distance in Sochi without oil, which will lead to dire consequences. When repairing a pump, it is worth replacing the sleeve with a bearing - they are much more reliable.
The entire set of solenoids is often changed along with the wiring. If one of the solenoids is out of order, it means that the rest will soon run out of their short life.Compared to the old generations of Kia Spectra automatic transmissions, the load on the solenoids has increased significantly, and their workmanship, on the contrary, has dropped. Sometimes the problem can be diagnosed by error codes or abnormal operation of third gear (hard shifting).
Of iron on this automatic transmission, the differential, its mounting bracket and plastic bearing quickly fail.

The Kia Sorento car is equipped with five-speed gearboxes RE5R05A from the Japanese "daughter" of Nissan Jatco. It has been installed since 2000 on powerful rear-wheel drive cars with an engine capacity of up to six liters.
The Kia Sorento transmission is very reliable and made with a large margin of safety. The first series of Kia Sorento automatic transmissions had an unpleasant feature, in which the transmission fluid was mixed with antifreeze, but later this defect was eliminated.
The big problem with the Kia Sorento automatic transmission was the hydraulic block. Since 2004, it has undergone constant modifications. The last modification of 2007, finally, turned out to be successful, and now these transmissions can compete in terms of fuel efficiency and shift speed with robotic gearboxes popular in Russia and Sochi, ahead of them in terms of resource and shift comfort.
The filter of this automatic transmission is reusable and must be flushed, except for cases related to contamination of the box with products of the decay of clutches.
To extend the life of the Kia Sorento automatic transmission, experts recommend installing a main fine filter.

The valve body in the old version of the Kia Sorento box was and remains a big headache for repair specialists. Too aggressive settings do not spare the gearbox and quickly wear out the torque converter lock, the remains of which get into the oil and wash out the hydraulic plate channels.
DO NOT SPEND MONEY ON REPAINING!
Now you yourself can remove any scratch from the body of your car in just 5 seconds.

Kia Rio cars were equipped with four-speed gearboxes from the Japanese manufacturer Mazda. The beginning of the installation of these automatic transmissions dates back to 1987, however, the automatic transmission has undergone constant improvements and modifications in the following years. The Kia Rio automatic transmission filter has not structurally changed since 1993 and Mazda cars.
Every third repair of the Kia Rio machine ends with the replacement of oil seals and gaskets of the torque converter, pump and valve cover. These are the weak points of the Kia Rio automatic transmission, due to which oil flows out of the box. The clutches of the Kia Rio automatic transmission are traditionally replaced with a set.
Often, due to wear of the solenoids of the Kia Rio automatic transmission, shocks occur when shifting gears, they are changed as a set.
Bushings and seals on older vehicles fail faster due to vibration.

Kia's transmissions are a lot like the sophisticated transmissions from Mitsubishi. Do-it-yourself repairs are possible only if you have knowledge, experience, a warm box with a lift and the necessary set of tools. Therefore, it is better to entrust this business to professionals who can be found in any city of Russia from Vladivostok to Sochi.
