Transmission run hot , often leading to transmission fluid oxidation, causing clutch glazing and deterioration in shift quality. Clutch glazing can be felt as an elongated, slipping or sluggish shifting feel, and it’s usually a precursor to transmission failure. AMSOIL Synthetic Universal Transmission Fluid (ATF) provides maximum protection against oxidation and clutch glazing.

Although differential designs have remained relatively unchanged over the past 30 years, their operating environments have changed drastically. Modern differentials are subjected to as much as 93 percent more horsepower, towing limits up to 18,000 lbs, extreme operating temperatures and decreased fluid volume.

The subject of proper engine maintenance has plenty of attention in the media, and most motorists are aware of its importance to the reliability and life of a vehicle. If the vehicle’s engine stops working, a motorist is stranded. Very little attention, however, has been given to the stresses encountered by a vehicle’s transmission or differential. Transmission and differential maintenance is just as important as engine maintenance. After all, if the transmission or differential stop working, the motorist is equally as stranded.

Only a few years ago, the standard automatic transmission was a three speed. Today four, five and six speed transmissions are common, and one manufacturer produces an eight speed transmission. Modern transmissions and differentials are subjected to more horsepower, higher towing limits and hotter temperature extremes, and they contain more clutches and are subjected to additional shifting for the same driving speeds. Wear protection and oxidation resistance, therefore, are more important than ever. AMSOIL Synthetic Automatic Transmission Fluid (ATF) provides excellent wear protection required for the GM DEXRON III and VI specifications and it resist oxidation two times longer than required for conventional automatic transmission fluids.
