Of all the fluids inside your vehicle, transmission fluid is one of the most important. This special type of fluid helps keep your car’s automatic or manual transmission cool and lubricated. Driving with low or dirty fluid inside the transmission can cause wear and tear that ultimately leads to unexpected transmission repairs.
Why It’s Important to Change Transmission Fluid
Regardless of whether you have a manual or automatic transmission, you will need to change the transmission fluid according to the service schedule in your owner’s manual. Automatic transmission fluid should be changed every 60,000 to 100,000 miles, while manual transmission fluid needs to be changed about twice as frequently, or every 30,000 to 60,000 miles. Over time, the fluid inside a transmission degrades and breaks down. Eventually, old fluids cease to keep all of the moving parts inside the transmission lubricated, which increased the amount of wear and tear on the transmission itself. Old transmission fluid also becomes contaminated with metal particles that can shorten the life of your transmission.
