Transmission fluid must be handled with extreme care to prevent the entry of what?

• A. Water
• B. Oil
• C. Air
• D. Contaminants

Answer: (D)

Keep transmission fluid clean because any foreign matter can disrupt lubrication and the hydraulic system it runs in. Contaminants—like dirt, metal particles, water, or sludge—can clog filters and narrow passages, wear gears and bearings, damage seals, and cause valve bodies or solenoids to malfunction. This leads to poor lubrication, reduced cooling, erratic shifting, and overall transmission wear or failure. Water and air are specific examples of contaminants, but the goal is to prevent any contaminants from entering, since even small amounts can have significant negative effects. So the best practice is to avoid introducing contaminants altogether by handling fluid in clean containers, keeping storage and transfer areas clean, and using proper filtration.
