Automatic transmission fluid is the lifeblood of any vehicle equipped with an automatic gearbox, performing far more than a simple lubrication role. Signs of Degradation and the Importance of Maintenance Because the fluid works under tremendous stress and heat, it gradually breaks down.
Automatic Transmission Fluid Warning Lights and What They Mean
When the driver selects a gear, the transmission control module signals a series of solenoids that direct pressurized fluid to specific clutches. As the fluid oxidizes and loses its frictional properties, the transmission computer may compensate by adjusting shift pressures and timing.
Left unchecked, the degraded fluid can no longer cool the system, leading to overheating, and the accumulated sludge can cause blockages that result in a complete loss of function, necessitating a full and expensive rebuild or replacement. Selecting the Correct Fluid Not all automatic transmission fluids are interchangeable, and using the wrong type can cause immediate damage.
Automatic Transmission Fluid Warning Lights: Understanding Low Fluid and System Issues
Automatic transmission fluid acts as the hydraulic medium, transmitting force from the valve body to these components with precision. Composition and Function Modern automatic transmission oil is a highly engineered fluid, far removed from the simple mineral oils of the past.
