Hello, My mom bought a RX300 (2003) with air suspension and her car face some issues. They had to change the gear box and now the gear oil is comin out. I don't know if it's because we're loosin oil but I don't feel the full power of the engine when I speed up. The height position of the car is currently on N but I can't change it. When we drive, the car bounce everytime. I have the lights VSC ASF illiminated on the board Could someone tell me how to fix this issues? Thanks
