- Incorrect fluid level: If the fluid level in the transmission is too high, it can cause the pump to push fluid out of the fill tube. Check the fluid level and make sure it is at the correct level.
- Damaged pump: A damaged pump can also cause fluid to be pushed out of the fill tube. If the pump is damaged, it will need to be replaced.
- Faulty pressure regulator: A faulty pressure regulator can cause the pump to produce too much pressure, which can force fluid out of the fill tube. If the pressure regulator is faulty, it will need to be replaced.
- Blockage in the cooling system: A blockage in the transmission's cooling system can cause the fluid to overheat and expand, which can force fluid out of the fill tube. Check the cooling system for blockages and clean it if necessary.
- Leaking gasket: A leaking gasket between the pump and the transmission case can also cause fluid to leak out of the fill tube. If the gasket is leaking, it will need to be replaced.
