The growing popularity of automatic transmissions means more vehicle owners are encountering various automatic transmission problems. They range from minor inconveniences to serious failures that require costly repairs. Below we will look at the most common symptoms and signs of automatic transmission faults and offer practical advice on how to deal with them and how to prevent them.

What are the most common problems with automatic transmission?

The automatic transmission is one of the most important technological achievements in modern cars. Despite the convenience and ease it provides, it is not immune to failures. Let’s see the most common problems with automatic transmissions and what measures can be taken.

1. Feeling of grinding or shaking in the gear

Symptoms of grinding and shaking in the gear often occur during acceleration or when shifting. They are caused by damaged gears or improper transmission operation. It is important not to ignore these signs, as early detection can prevent larger and more expensive repairs. Regular inspection and automatic transmission oil changes are key to preventing such problems.

2. The car does not engage or respond when in gear

Common causes for this can be worn parts, contaminated or low transmission fluid level, or loss of its protective properties. In such cases, when the car does not shift, it is necessary to check the color and level. If it is dark red and thick, change it. If it is insufficient, top up the fluid.

3. Makes noises: whining, humming or knocking, noisy in neutral

These unpleasant noises are often due to worn components or insufficient lubrication. If you hear such sounds, do not hesitate to consult a qualified mechanic and have the fluid replaced.

4. Smells like burning

A burning smell from the car can be an alarming sign of overheating of the automatic transmission. Overheating is usually caused by low transmission fluid level or topping up with the wrong fluid. If you notice a burning smell, check the level and condition, and if the smell persists – visit a service center.

5. Gear slipping

Gear slipping, felt as slipping or jerking, is another common problem with automatic transmissions. The causes are usually related to a problem with the computer that tells the car when to shift and when power should be sent to the wheels. It can also be due to damage to the transmission gears. If you notice such a symptom, it is important to have a diagnostic check immediately and seek a service for automatic transmission repair to prevent further damage. If the problem turns out to be in one of the components – transmission replacement may be required.

6. Low transmission fluid level or leakage

An insufficient amount is caused by leaks, which lead to automatic transmission malfunction. It is important for lubrication and cooling of the transmission. To keep the automatic transmission in good condition, regularly check the transmission fluid level and watch for possible leaks. If you notice reduced levels or traces of fluid under the vehicle, take immediate action to top up and locate the leak. A repair will be necessary, often involving replacement of the transmission filter, hose or seal.

7. Check whether the engine light (the check) is on

The engine light (known as the "check" light) can illuminate for various reasons, including transmission problems. If you notice this light, do not ignore it. Modern cars are equipped with computer systems that can diagnose and warn about potential problems. When the "check" light comes on, seek professional help for accurate diagnostics using specialized equipment to find the exact cause and repair it.

What should you do?

Here is what you can do to minimize damage and ensure the long-term operation of your vehicle.

1. Check the level and condition of the transmission fluid

Make sure it is within the recommended limits and that there are no traces of leaks under the vehicle. Have annual diagnostics performed at a specialized service.

2. Use a product with the correct specifications

Consult the vehicle manual or a specialist before purchasing and filling the fluid. For some brands, like Mercedes and Audi, it is usually recommended to use the original fluid.

3. Regularly replace the transmission filter

Do this at every automatic transmission fluid change to ensure the system's efficiency.

4. Avoid towing heavy loads or pulling other cars

If you need to tow heavy loads, use a vehicle with a manual transmission to avoid overheating and oxidizing the fluid.

5. Periodically check the vehicle's cooling system as well

Maintain the cooling system, which helps cool the transmission fluid.

6. Before starting, let the car warm up for a while

During winter months, let the car warm up before driving; this is necessary to protect the transmission. Remember that timely action at the first signs of a fault is key to the long-term operation of your vehicle.

The importance of regular maintenance and diagnostics

Regular maintenance and diagnostics of the automatic transmission are essential for its correct and long-term functioning. Periodic fluid changes, level checks, and regular inspections by a specialist will help you avoid costly repairs.

Invest in quality oils and filters to ensure optimal performance of your vehicle. Remember that regular maintenance not only extends the life of your transmission but also ensures road safety.
