What should you check every 15,000 miles?

Checking the automatic transmission fluid every 15,000 miles is crucial because this fluid plays a key role in the proper functioning of the vehicle's transmission system. It lubricates the moving parts within the transmission, helps cool it, and ensures smooth shifting between gears. Regularly checking the level and condition of the transmission fluid allows you to identify potential problems early, such as leaks or deterioration of the fluid, which can help prevent costly repairs down the line. Neglecting to monitor this fluid can lead to transmission failure, which is one of the most expensive issues a vehicle can face.

Staying on top of this maintenance helps ensure the longevity and efficiency of your vehicle's performance.
