When should you replace your vehicle’s transmission fluid?
Intervals for changing transmission fluid vary from every 45 000 km to a “life-time” fill.
Reference to a “life-time” fill is based on the expected life-time of your vehicle in the home markets.
South Africans tend to use vehicles longer. Autoworks, in line with most experts overseas, recommends changing the transmission fluid after 10 years or 200 000 km.
Like other fluids, transmission fluid deteriorates over time. Hard use like, driving in traffic, heavy loads and towing a trailer will speed up deterioration.
If you don’t change the transmission fluid on schedule, you’ll be lubricating your transmission with metal shavings and other contaminants. This will shorten the transmission’s life.
Also remember, unlike engine oil, transmission oil doesn’t burn up. So if you’re low on transmission fluid, you almost certainly have a leak.
