Why is it important to regularly check the transmission fluid in a school bus?

Regularly checking the transmission fluid in a school bus is crucial for ensuring optimal performance and longevity of the transmission. Transmission fluid serves multiple essential functions: it lubricates the moving parts within the transmission, provides hydraulic pressure necessary for gear engagement, and helps to dissipate heat generated during operation. If the fluid level is low or if the fluid is dirty, the transmission may not operate effectively, leading to shifting issues, increased wear on components, and potential failure over time. Maintaining the proper fluid level and ensuring its cleanliness supports the overall operation of the bus and can prevent costly repairs, thereby enhancing the bus's reliability and service life.
