The Critical Role in Hydraulic Pressure Unlike manual transmissions that rely on physical linkage to engage gears, automatics use a complex network of hydraulically operated clutches and bands. Choosing a fluid that meets the original equipment manufacturer (OEM) standard is non-negotiable for warranty compliance and optimal performance, ensuring the transmission shifts smoothly and reliably for years to come.

These specifications dictate the exact frictional characteristics required for the transmission’s clutch packs. Contaminants such as metal shavings from worn gears and clutch material build up over time, turning the fluid a murky brown or even black.
The base stock is typically a refined petroleum product or a synthetic blend, chosen for its thermal stability and viscosity index. This can result in increasingly erratic shift patterns, such as noticeable lag, harsh upshifts, or slipping between gears.
Automatic Transmission Fluid Additive Review: Boosting Performance and Protecting Your Transmission
When the driver selects a gear, the transmission control module signals a series of solenoids that direct pressurized fluid to specific clutches. Additives are then precisely formulated to create a multi-tasking fluid that includes anti-wear agents to protect gears, friction modifiers to ensure clutch engagement, detergents to keep the system clean, and oxidation inhibitors to prolong life.
