1. Lubrication Problems: Transmission oil has different properties and viscosity compared to power steering fluid. It may not provide the necessary lubrication for the power steering pump, rack, and other components. This can lead to increased wear and tear, reduced performance, and eventually system failure.
2. Seals Damage: Transmission oil can cause seals and hoses within the power steering system to swell, deteriorate, or become brittle over time. This can lead to leaks and loss of fluid, affecting the system's performance and causing further damage.
3. Foaming: Transmission oil is not designed to withstand the high pressures and temperatures generated in the power steering system. It may foam or aerate, creating air bubbles that can lead to reduced fluid flow, cavitation, and reduced system efficiency.
4. Corrosion: Some transmission oils may contain additives that can cause corrosion of the metal components within the power steering system, such as the pump, rack, and lines.
5. Pump Damage: Using transmission oil in the power steering system can put additional strain on the power steering pump. The pump may have to work harder to circulate the thicker transmission oil, leading to increased wear and tear or even pump failure.
6. System Failure: If the transmission oil causes significant damage to seals, hoses, or components, it can result in complete failure of the power steering system. This could lead to loss of steering control and compromise vehicle safety.
It is important to use the correct type of fluid specified by the manufacturer for your vehicle's power steering system. If you accidentally add transmission oil to the power steering reservoir, it's highly recommended to flush the entire system and replace it with the proper power steering fluid as soon as possible to avoid potential damage.
