Automatic transmissions (AT) have become an integral part of modern cars, providing comfort and convenience in control. However, to maintain reliable operation of the AT and extend its lifespan, oil changes are required. In this article, we will discuss the importance and process of oil changes in the transmission.
Oil Change in AT: Why is it Important?
Changing the oil in the AT is a procedure that is critical for the reliable operation of the vehicle. Here are several key reasons why this is so important:
-
Lubrication and Cooling: The oil in the AT plays an important role in lubricating and cooling various parts and mechanisms, preventing wear and overheating.
-
Friction Reduction: The right oil reduces friction between parts, contributing to the smoothness and efficiency of transmission operation.
-
Contaminant Removal: During operation, metal particles and other contaminants enter the oil, which can lead to wear. Changing the oil allows for the removal of these particles.
When Should Oil Be Changed in AT?
Changing the oil in the AT is necessary, but the time intervals may vary depending on the make and model of the vehicle. It is generally recommended to change the oil every 30,000 - 60,000 miles (approximately 48,000 - 96,000 kilometers). However, pay attention to the following signs that may indicate the need for a change:
-
Noises and Jerkiness: If you hear unusual sounds or feel jerks when shifting gears, this may be a sign of oil wear.
-
Overheating: Overheating of the AT can cause redness and deposit formation in the oil. This also indicates the need for a change.
-
Loss of Performance: If you notice that the vehicle has become less responsive and shifts gears slower, this may be related to oil wear.
Oil Change Process in AT
Changing the oil in the AT is a process that requires specific skills and specialized tools. Here is the general process:
-
Prepare the Vehicle: Make sure the vehicle is on a level surface and parked in a safe place. Also, ensure that the engine is off and the handbrake is activated.
-
Lift the Vehicle: Lift the vehicle using a jack and set it on stands to provide access to the oil reservoir.
-
Oil Drainage: Open the AT oil reservoir and remove the cap to drain the oil. Drain the old oil into an appropriate container.
-
Oil Replacement: Close the drain cap and fill the reservoir with new oil, using the specifications recommended by the vehicle manufacturer.
-
Check the Level: After filling with oil, ensure that the level matches the manufacturer's recommendations. Add oil if necessary.
-
Complete the Procedure: Close the oil reservoir, lower the vehicle from the stands, and check for oil leaks.
Changing the oil in the AT is an important procedure to ensure the reliable operation of the vehicle. Proper maintenance of the transmission helps prevent wear and ensures comfortable driving. Following manufacturer recommendations and timely oil changes contribute to the long lifespan of the AT and maintaining high vehicle performance.
