Liqui Moly ATF Additive helps prevent and fix leaks in automatic transmissions and steering gears by rejuvenating hardened or brittle seals. It cleans internal components, reduces noise, improves shifting, and extends system life. Simply mix the 250 ml additive into the gear oil via the dipstick or into the power steering reservoir; suitable for up to 8 liters of ATF II or ATF III oil.
