ZAZ Chance cars with a 1.4 engine and automatic transmission represent a unique combination of a budget Korean platform and availability on the post-Soviet market. For many drivers, availability Automatic transmission in this class it became a decisive factor in the purchase, since the mechanics in city traffic jams quickly tire. However, an automatic transmission requires a special approach to operation and maintenance, different from conventional mechanics.
Unlike modern robots or CVTs, a classic 4-speed hydromechanics, time-tested, is installed here. This technology is considered one of the most reliable, but even it has its limits of strength and service life. Understanding the operating principles of the unit will help the owner avoid costly breakdowns and extend the life of the unit by hundreds of thousands of kilometers.
It is important to immediately note that the service life of the box directly depends on the quality of service and driving style. Many of the problems that owners encounter could be prevented by regularly changing the fluid and filters. Ignoring simple rules often leads to major repairs, the cost of which can be a significant part of the market price of the car itself.
Transmission design features
ZAZ Chance with a 1.4-liter engine is equipped with a 4-speed automatic transmission developed by Daewoo. Structurally, this unit belongs to classic torque converter boxes. The basis is a planetary gear set, which ensures gear shifting without interrupting the power flow. The torque converter here acts as a clutch, transmitting torque from the engine to the transmission through fluid.
Shift control is carried out by a hydraulic unit, often called a "valve block" or "valve plate". It is the solenoids located on this block that supply oil under pressure to the required channels, activating the clutch packs. Electronic part The system is represented by speed sensors at the input and output, as well as a selector position sensor. The entire system is controlled by the TCM, which reads the gas pedal and engine speed.
⚠️ Attention: The hydraulic unit is a very sensitive element of the system. The ingress of even the smallest metal shavings or friction wear products can lead to valve jamming and costly repairs.
A special feature of this model is the absence of a separate oil cooling radiator in the basic configuration; air cooling or a heat exchanger is often used in the engine cooling system. This makes the system sensitive to overheating during prolonged driving in traffic jams or towing trailers. Temperature is a critical factor for durability.
Technical characteristics of the gearbox
Model: Daewoo A14DMS (similar to Aisin). Number of gears: 4. Control type: Hydraulic with electronic control. Lifetime before overhaul: 150-200 thousand km (with proper care).
Frequent malfunctions and their symptoms
Despite its overall reliability, the ZAZ Chance 1.4 automatic machine is not without “childhood diseases” and age-related problems. Owners often experience kicking when changing gears, especially when moving from first to second or when releasing the gas. This may indicate worn friction discs or pressure problems in the system.
Another common problem is floating speed and “thoughtiness” of the box during acceleration. Often this is not due to the mechanics themselves, but to incorrect operation throttle position sensor (DPDZ). If the control unit receives incorrect data about the engine load, it cannot correctly select the moment to change gear.
- 🔴 Kicks and jerks when shifting gears often indicate low oil levels or contamination of the valve body.
- 🟠 A hum or howl that increases in speed may indicate bearing wear or problems with the torque converter.
- 🟡 If the "Check Engine" indicator lights up or the "S" mode light flashes on the selector, it indicates an electronic error in the control system.
It is worth mentioning separately about oil leaks. The drive seals and the selector rod seal become tanned over time and begin to leak fluid. A drop in ATF level leads to oil starvation, which is deadly for the machine. Visual inspection space under the car after parking should become a habit.
Selection of oil and technical fluids
Choosing the right transmission fluid is key to long life for your transmission. For ZAZ Chance 1.4 automatic, the manufacturer recommends using fluids that meet the specifications Dexron III or more modern analogues Dexron VI. Using the wrong oil can lead to changes in friction properties and incorrect operation of the torque converter.
The amount of oil in the system depends on the replacement method. With a partial replacement, when only what is in the pan is drained, the volume is about 5.5–6 liters. A complete hardware replacement using the displacement method may require up to 10–12 liters of fluid.
| Parameter | Meaning/Recommendation | Note |
|---|---|---|
| Specification | Dexron III / Dexron VI | Use of compatible analogues is allowed |
| Volume (partial replacement) | ~6.0 liters | Requires 2-3 times replacement to update |
| Volume (full replacement) | ~10-12 liters | Hardware preemption method |
| Replacement interval | 40,000 - 60,000 km | Depends on operating conditions |
⚠️ Attention: Never use oils marked CVT or DCT in the classic ZAZ Chance hydromechanical gearbox. This will lead to rapid failure of the unit.
When purchasing oil, pay attention to the color of the liquid. Fresh automatic transmission oil usually has a red or green tint (depending on the brand), but the main thing is transparency. If the fluid smells burnt or is black in color, this is a sign that the clutches are seriously worn and require repair.
Oil and filter change process
The procedure for changing the oil in a ZAZ Chance 1.4 automatic transmission requires certain preparation and the availability of tools. To work, you will need new ATF fluid, an automatic transmission filter (mesh), a pan gasket or sealant, and a set of keys. Before starting work, the car must be placed on a flat surface and the box must be warmed up to operating temperature.
☑️ Preparing for an oil change
First, unscrew the drain plug or carefully remove the pan so as not to damage the gasket. The old oil is poured into the prepared container. Then you need to remove the old coarse filter (mesh) and thoroughly rinse the tray to remove metal shavings that inevitably accumulate on the magnets. Installing a new filter is mandatory, as the old one clogs quickly.
After assembling and pouring new oil through the dipstick hole (or filler neck), you need to start the engine. After warming up the oil to 60–80 degrees, you need to go through all the selector positions (P-R-N-D), lingering in each for a few seconds. The level is checked with the engine running; the dipstick must be wiped clean before the final measurement.
When removing the pan, carefully inspect the magnets. If there are large metal shavings or “mess” on them, this is a bad sign that requires diagnostics of the mechanical part of the box.
Diagnostics and adaptation of the gearbox
Modern cars, including ZAZ Chance, are equipped with a self-diagnosis system. If a malfunction occurs, the control unit puts the box into emergency mode, recording an error code. To read these codes, you need an OBD-II scanner or a specialized diagnostic adapter that is connected to a connector in the passenger compartment.
After changing the oil, repairing or replacing the battery, an adaptation procedure is often required. The electronic control unit “forgets” the driver’s habits and resets the pressure settings. Adaptation allows the box to relearn smooth shifting for specific clutch wear and driving style.
The adaptation process usually looks like this: warming up the engine, sequentially switching all modes with pauses, then driving in various modes (calm and dynamic) for a certain time. Some dealer scanners allow you to launch a forced adaptation reset procedure through the menu Special Functions.
- 🔵 Error P0700 indicates a general malfunction of the transmission control system.
- 🟣 Error P0715 indicates a problem with the turbine input shaft speed sensor.
- 🟢 The P0720 code is related to the output shaft speed sensor, which often causes jerking.
Tips for operation and service life extension
In order for the ZAZ Chance 1.4 automatic transmission to serve for a long time, you must adhere to the rules of “warm” operation. In winter, it is imperative to warm up the unit before driving. To do this, while holding the car on the brake, you should turn on all selector modes one by one, holding each mode for 5–10 seconds. This will disperse the oil through the system.
Avoid sudden starts from a standstill (“launch control” is not for budget cars) and frequent lane changes in traffic jams with active use of the gas pedal. Torque converter does not like sudden load surges when cold. Also try not to skid in snow or mud - if the car stops, it is better to put boards or use help than to accelerate.
⚠️ Attention: When towing a car with the engine not running, the speed should not exceed 40 km/h and the distance should not exceed 50 km. Otherwise, the components are not lubricated enough and the box may jam.
Regularly check the condition of the seals and the absence of oil stains under the machine. Timely replacement of even a small amount of lost oil will save you from major repairs. Remember that the oil level is more important for the machine than for the engine.
The main secret to the longevity of the ZAZ Chance automatic transmission is frequent (every 40 thousand km) partial oil changes and mandatory warming up in winter before the trip.
Questions and answers (FAQ)
Is it possible to tow other cars with a ZAZ Chance with an automatic transmission?
Towing other cars with a ZAZ Chance with automatic transmission is highly not recommended. The design of this 4-speed gearbox is not designed for high traction loads when towing, which will lead to rapid overheating of the oil and wear of the clutches.
Why does the box only kick when it's cold?
Cold kicks are often associated with thickened oil or loss of elasticity of the piston sealing rings. After warming up, the rubber softens and the pressure returns to normal. It is also worth checking the fluid level.
How often do you need to change the oil in a ZAZ Chance automatic transmission?
Although the manufacturer may indicate longer intervals, for city conditions and traffic jams partial replacement every 40,000 - 50,000 km is considered optimal. This significantly extends the life of the valve body.
What does the flashing "S" on the selector mean?
A flashing "S" (Sport) or "Check" indicator indicates that the control unit has detected an error in the transmission and has entered emergency mode. A computer diagnostic is required to read the trouble code.
