1. Transmission Damage: Steering fluid is not formulated for the lubrication requirements of a transmission. It lacks the necessary additives and properties to withstand the high pressure and friction generated within a transmission. Using steering fluid can lead to increased wear, damage to gears and bearings, and reduced transmission performance.
2. Slipping Gears: Steering fluid has a lower viscosity compared to transmission fluid. This means it provides less resistance to the movement of gears, resulting in slipping. Slipping gears can cause incomplete or delayed shifting, reduced power transfer, and increased wear on transmission components.
3. Overheating: Steering fluid has a lower boiling point compared to transmission fluid. When subjected to the higher temperatures generated in a transmission, steering fluid can boil and turn into vapor, leading to overheating. Overheating can damage transmission seals and internal components, causing fluid leaks and accelerated wear.
4. Seal Damage: Steering fluid is not compatible with transmission seals and gaskets. Using it can cause these seals to swell, deteriorate, or harden, compromising their sealing ability. This can lead to fluid leaks, loss of pressure, and further damage to transmission components.
5. Reduced Transmission Life: The cumulative effect of these issues mentioned above can significantly reduce the lifespan of the transmission. Improper lubrication, slipping gears, overheating, and seal damage can hasten wear and tear, requiring costly repairs or even transmission replacement.
It's important to note that if you accidentally add steering fluid to the transmission, it is crucial to drain and flush the transmission as soon as possible and refill it with the correct transmission fluid to minimize damage. Consulting a professional mechanic or referring to the vehicle's owner manual is always recommended to ensure the correct fluids are used in your vehicle.
