PRODUCT DESCRIPTIONAMSOIL Synthetic Tractor Hydraulic/Transmission Oil is an all-weather Universal Tractor Transmission Oil (UTTO) engineered to meet the tough demands of heavy-duty, hydraulic-powered farm and commercial equipment. Its unique formulation of synthetic base stocks and additives effectively reduces wear, resists heat, protects against rust and extends fluid and equipment service life. Synthetic Tractor Hydraulic/Transmission Oil is recommended for extended oil drains based on oil analysis.
Excellent Protection in Temperature Extremes AMSOIL Synthetic Tractor Hydraulic/Transmission Oil operates over a wide range of temperatures. It has a high viscosity index to maintain its lubricity for wear protection at high operating temperatures, and it flows at temperatures down to -58°F (-50°C) for improved equipment operation at low temperatures. Synthetic Tractor Hydraulic/Transmission Oil exceeds the viscosity requirements of the all-weather specifications of both Case New Holland 3525 and 3526 (formerly Ford New Holland FNHA-2-C-200 & 2-C-201) and John Deere J20C & J20D, helping eliminate the need for seasonal oil changes.
Amsoil Synthetic Tractor & Transfer Case Oil is one of the best oils we have found for the Duramax Diesel 4x4 261XHD and 263XHD transfer case found in the 2500 and 3500 HD 4x4 pick up trucks.The Dmax Transfer case takes 2 qts of this fluid. We also suggest you buy the hand pump to install this fluid. The fill hole on the transfer case is conveniently hidden by a cross member so you can't get a funnel in the fill hole. If you have a 2001-2010 you may want to buy and add the magnetic drain plug set to install on your transfer case also.
