Lubegard ATF Protectant has been designed to attack an automatic transmission’s number one enemy: heat. It incorporates a unique, patented synthetic LXE (Liquid Wax Ester) technology which increases the thermal stability of transmission fluid. This, in turn, reduces oxidation and acid formation that can lead to sludge and fluid degradation. The company says Lubegard reduces transmission fluid heat by up to 40ºF, which can dramatically increase transmission life.
