The period for changing the oil in an automatic transmission varies depending on the type of gearbox, vehicle and operating conditions. Below are general recommendations:
Traditional automatic transmissions (AT):
* Normal operating conditions: 30,000 – 60,000 km or 2 – 3 years
* severe operating conditions: (frequent towing, driving in traffic jams, extreme temperatures) 15,000 – 30,000 km or 1 – 2 years
Variable speed transmissions (CVT):
* Normal operating conditions: 45,000 – 60,000 km or 4 – 5 years
* severe operating conditions: 30,000 – 45,000 km or 2 – 3 years
Double Clutch Transmissions (DCT):
* Normal operating conditions: 50,000 – 75,000 km or 5 – 6 years
* severe operating conditions: 25,000 – 50,000 km or 2 – 4 years
Automatic Manual Transmissions (AMT):
* Normal operating conditions: 50,000 – 60,000 km or 4 – 5 years
* severe operating conditions: 30,000 – 45,000 km or 2 – 3 years
It is important to note that these are just guidelines. Always check your vehicle’s owner’s manual for specific oil change intervals for your transmission. And also pay attention to the following signs indicating the need for an oil change:
*Low oil level
* Contaminated oil (black)
* Strange sounds or vibrations when shifting gears
* Slippage or delay when shifting gears
