Product overview
ATF Additive provides conditioning care for the rubber and plastic seals inside both steering gears and automatic transmissions. Leaks caused by hardened or brittle seals in either system are prevented or addressed by the treatment, which also cleans the internal holes and ducts to help revitalise the performance of the ATF fluid already in place.
Because it works on the fluid's own performance rather than replacing it, the treatment can reduce noise and improve the smoothness of automatic-transmission shifting, while also extending the working life of the steering gear or transmission it is added to.
