Can Power Steering Fluid and Transmission Fluid Be Used Interchangeably?
1 Answers
Power steering fluid and transmission fluid cannot be used interchangeably, as they serve different purposes and have distinct properties. Transmission fluid is primarily designed to keep the gear system clean and to lubricate the transmission components, thereby extending their lifespan. Depending on the transmission design, it can be categorized into manual transmission and automatic transmission. Each transmission model has unique technical requirements, and even the same transmission model installed in different vehicle types may vary in torque, weight, rotational speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluid. Power steering is a comfort-enhancing technology in vehicles that automatically provides steering assistance, reducing the driver's steering effort. Power steering fluid is a medium oil added to the power steering system, serving to transmit steering force and provide cushioning.
