Febi Bilstein 33889 Automatic Transmission Fluid - Purpose and Specifications

Keep your Mercedes-Benz 722.9 automatic transmission running smooth and reliable with Febi Bilstein 33889 ATF. This blue 1-liter fluid meets exact MB 236.15 and ATF 134 FE specs for transmissions from number 2834527 onward. It delivers top protection against freezing in cold starts down to -40°C, fights corrosion to protect metal parts, and stays stable up to 150°C for hot towing or city driving.
