DEXRON Chemical compatibility with O-rings, rubbers, & plastics

Dexron, a trade name for a family of automatic transmission fluids, is widely used in automotive drivetrains to provide lubrication, oxidation resistance, and protection against wear and corrosion. These transmission fluids may come into contact with O-rings, rubber seals, gaskets, and plastic components, so material compatibility should be evaluated to prevent swelling or hardening. While generally safe when handled properly, exposure can cause irritation. Appropriate storage conditions, careful handling practices, and the use of suitable PPE are recommended.
