Lucas Automatic Transmission Fluid Conditioner is designed to provide ATF’S with enhanced performance. Our unique Lucas additive chemistry prolongs fluid life, reduces wear, conditions seals, reduces noise and shudder and maintains cold temperature properties even under the most adverse conditions. It is designed as a preventative measure in both new and older foreign and domestic transmissions and is compatible with both synthetic and conventional ATF’S. We do not recommend for use in CVT, and Ford Type F transmissions.
