Is Power Steering Fluid the Same as Transmission Fluid?

[DiAlejandro]

Power steering fluid and transmission fluid are not the same. Transmission fluid can be used as power steering fluid in a car, but power steering fluid cannot be used as transmission fluid. Here are some introductions about power steering fluid and transmission fluid: 1. The main function of transmission fluid is to keep the gear shifting system clean, and to lubricate and extend the service life of the car's transmission device. 2. Power steering fluid is mainly to increase driving comfort. When the driver is driving the car, it automatically provides steering force, making the driver's driving process easier, and it can also reduce the driver's steering fatigue.

I believe power steering fluid and transmission oil have distinct differences. Power steering fluid focuses on steering assist performance with a lightweight formula, while transmission oil is optimized for smooth gear shifts requiring viscosity and stability. Misuse can easily damage components and lead to high repair costs. It is recommended to differentiate maintenance to ensure smooth driving.
