These specifications dictate the exact frictional characteristics required for the transmission’s clutch packs. Automatic transmission fluid is the lifeblood of any vehicle equipped with an automatic gearbox, performing far more than a simple lubrication role.
Understanding Automatic Transmission Fluid Types and Specifications
Vehicle manufacturers specify the exact formulation required, often denoted by a unique Ford WS, GM DEXRON, or Toyota WS standard. This can result in increasingly erratic shift patterns, such as noticeable lag, harsh upshifts, or slipping between gears.
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. A burnt smell is a particularly clear indicator that the fluid has exceeded its thermal limit, causing the additive package to break down.
Understanding Different Automatic Transmission Fluid Types
The base stock is typically a refined petroleum product or a synthetic blend, chosen for its thermal stability and viscosity index. Fluid Change Intervals Manufacturer recommendations for fluid change intervals vary significantly, ranging from a severe 30,000 miles to a "lifetime" claim that can exceed 100,000 miles.
