What happens if too much transmission fluid is added?

[BentleyDella]

Adding too much transmission fluid can cause the following symptoms: 1. The automatic transmission may leak oil. If the transmission fluid level is too high, the rotating components will come into contact with the fluid during operation. Under the high-speed stirring of components such as planetary gear sets or clutches, the fluid may expand and boil, causing it to leak out from the filler hole and vent valve. 2. It can cause gear shift shock. Excessive air entering the fluid can also lead to air blockage in the drain holes of the control valve body, resulting in poor drainage and causing gear shift shock. 3. It can result in low working oil pressure. If the transmission fluid level is too high, the rotating components will stir the fluid, creating bubbles. When this aerated fluid enters the oil pump, the pump cannot establish the required oil pressure.
