Although replacing your transmission fluid is necessary, the best interval depends on the type of transmission you have. Most manufacturers advise replacing the fluid between 30,000 and 60,000 miles if you drive manually. That range may often be increased to 60,000 to 100,000 miles if you have an automatic vehicle.

It is safe to change your fluid early. Heavy-duty drivers who operate their manual transmission vehicles may wish to change the fluid every 15,000 miles. Similarly, you might need to replace the fluid in your automatic transmission every 30,000 miles in some cases.

The best course of action to determine the specific interval for your vehicle is to check your owner’s manual or a qualified mechanic.

What happens if you never change transmission fluid?

When you replace the fluid in a car, particles and dirt are flushed away. These will continue to circulate in the transmission if you never empty the fluid. They may not harm the transmission, but when the miles add up, they actually help the transmission shift correctly.

Can I just add transmission fluid?

You may add additional by placing a funnel inside the tube that the dipstick was removed from and squirting some ATF within the pipe. Up until the level is exactly between the two lines, check the level after each addition.
