Different fluids have different formulations and additives that are designed specifically for their intended applications. While transmission fluid and power steering fluid may have some similar properties, they are not interchangeable without risk. Power steering fluid is specially formulated to withstand the pressures, temperatures, and conditions of your vehicle's power steering system, which may differ from the requirements of the transmission.
Mixing or substituting fluids that are not recommended by the vehicle manufacturer can compromise the performance and durability of your power steering system. This can lead to issues such as reduced steering performance, increased wear on system components, fluid leaks, and potential damage to the power steering pump and other parts of the system.
To ensure proper functioning and longevity of your vehicle's power steering system, it is essential to use the Dexron 2 power steering fluid as recommended in your 1992 Toyota Camry's owner's manual. If you have doubts or concerns about selecting the right fluid, it is best to consult with a professional mechanic or a reputable automotive parts store for the appropriate Dexron 2 power steering fluid.
