Differentials deliver the power from transmission to wheels. Extreme high operating temperatures can cause thermal breakdown of the differential fluid, leading to a loss of lubrication and deposit formation. This can cause gears to grind while leaving behind metal shavings and other debris.

Benefits of Differential & Transfer Case Fluid Service

Our Valvoline™ Differential and Transfer Case Services (Gearboxes) using Valvoline Professional Series products are thermally stable and help remove deposits – while working to keep new ones from forming. This helps to ensure proper gear lubrication.

Mileage Interval

Many vehicle manufacturers recommend fluid replacement at regular intervals to maintain vehicle performance. Please consult your owner’s manual for specific manufacturer recommendations.
