What is a common sign of low transmission fluid?

A common sign of low transmission fluid is difficulty in shifting gears. This occurs because transmission fluid is essential for lubricating the moving parts within the transmission and ensuring smooth operation. When fluid levels are low, the lubrication decreases, which can lead to increased friction and wear within the transmission, resulting in hesitation or grinding when attempting to shift.

Additionally, low transmission fluid can also cause the transmission to overheat, leading to further complications and potential damage. It's important for vehicle maintenance to regularly check and maintain proper transmission fluid levels to ensure that the transmission operates smoothly and without issues.
