As your vehicle gets older it demands more from the transmission fluid, which often causes the fluid to shear. When the transmission fluid begins to degrade, oxidation occurs, which leads to rough shifting, slipping and increased temperature. As a result of the increased temperature, the rubber seals and gaskets inside the transmission will begin to harden and may create leaks. Slick 50® Recharged High Mileage Automatic Transmission Treatment is specially formulated with additional additives for vehicles over 75,000 miles to restore and protect your vehicle's performance. Slick 50® Recharged Automatic Transmission Treatment helps to extend your vehicle’s transmission life. NOTE: Use only per label directions. DIRECTIONS: Always check and follow owner manual’s automatic transmission fluid specifications, compatibilities, and procedures. 1. Keep product at room temperature (above 55°F). 2. Engine should be “warm” and running before and during application. 3. SLICK 50® Recharged High Mileage Automatic Transmission Treatment has a “dripless” gel consistency.
