BG Premium Full Synthetic ATF provides superior protection to ensure a long transmission life. Automatic transmissions are more sophisticated than ever. They operate under extreme conditions: heat, moisture and close gear tolerances. These conditions contaminate and shear ordinary automatic transmission fluids to the point they no longer perform well, robbing a vehicle of power and performance. Worn-out automatic transmission fluid can leave deposits and debris in the transmission that could eventually ruin it. An essential part of the BG Transmission Service, BG Premium Full Synthetic ATF is the superior choice to use in all passenger and commercial automatic transmissions. It meets or exceeds the performance criteria of JASO 1-A and many other automatic transmission fluids. It provides excellent protection of gears and offers superior thermal stability, anti-wear protection, outstanding oxidative stability, foam resistance and corrosion control, exceptional low temperature fluidity and shear stability to ensure a long service life. Installed by a professional technician, it provides outstanding protection for automatic transmissions. BG Premium Full Synthetic ATF is NOT intended for use in continuously variable transmissions (CVTs) or in transmissions requiring Type F fluid. BG Premium Full Synthetic CVT Fluid can be used in the BG Transmission Service.
