Why is it important to regularly check the automatic transmission fluid level?

Regularly checking the automatic transmission fluid level is crucial because the fluid plays a vital role in the overall functionality of the transmission system. It serves multiple purposes, including lubrication of moving parts, cooling the transmission components, and facilitating smooth gear shifts. If the fluid level is too low, it can lead to insufficient lubrication, which increases wear on components and may result in overheating. Over time, this can cause severe damage to the transmission system, leading to costly repairs. Maintaining the correct fluid level ensures that the transmission operates efficiently and extends its lifespan.
