A Scientific FactTests prove that TranSynd™ will outperform other oils on every level:
Gears, bearings, bushings, clutches, thrustwashers and other components benefit from improved viscosity stability and cooler lube oil.The Numbers Prove ItExtended oil change guidelines for TranSynd™ include 50,000 miles/24 months for Severe duty and for General duty, 100,000 miles/48 months, once a 90%+ fill of TranSynd™ has been reached. (Reference Allison Service Tip #1099B for more information on how to achieve the appropriate fill of TranSynd.) Compare that to conventional transmission fluid recommended changes of 12,000 miles/6 months for severe duty. And 25,000 miles/12 months for general duty.
