When to Change Transmission Fluid for Automatic Cars?

[DiMiguel]

Automatic cars should have their transmission fluid changed every 2 years or 60,000 kilometers. Transmission fluid ensures smooth gear shifting, lubricates internal transmission components, and prevents damage during gear changes. Expired or deteriorated transmission fluid can lead to difficult gear engagement and wear on transmission bearings. The steps for changing transmission fluid are: 1. Start the engine to warm it up, allowing the transmission to reach operating temperature, then remove the drain plug to collect the old fluid; 2. After the old fluid has completely drained, open the oil pan, replace the transmission filter, reinstall the oil pan and drain plug; 3. Add new transmission fluid, start the car, and shift through all gears; 4. Check if the automatic transmission fluid level is normal and make adjustments as needed.
