What does excessive transmission fluid level indicate?

Excessive transmission fluid levels can indeed lead to shifting problems. When the fluid level is higher than the manufacturer's specified range, it can create excess pressure within the transmission. This increased pressure can lead to aeration of the fluid, which diminishes its lubricating properties and can result in erratic shifting, harsh engagements, or slipping. In addition to affecting performance, excessive fluid can also cause foam, which negatively impacts the hydraulic systems responsible for proper gear engagement. Therefore, maintaining the correct transmission fluid level is crucial for ensuring smooth operation and longevity of the transmission system.
