Chrysler Dodge Mopar ATF +4

Chrysler Dodge Mopar ATF+4 specification — this is the official transmission fluid approval developed by Stellantis for automatic gearboxes of Chrysler, Dodge, Jeep and Ram models. ATF+4 must meet strict viscosity requirements (typical range 6.0–7.5 cSt at 100 °C), high‑temperature stability, oxidation protection, anti‑foaming and provide the required friction coefficient for smooth shifting and durability of the hydraulic torque converter. This specification is intended for a wide range of transmissions, including 4‑, 5‑, 6‑, 8‑speed automatic gearboxes, as well as variants with a dual‑converter, installed in gasoline, diesel and turbocharged engines of these brands. ATF+4 is compatible with exhaust after‑treatment systems because it contains no sulfate additives that could damage catalysts, and it simultaneously supports DPF operation in diesel models. When choosing XENUM fluid, such as XA‑TRAN DX VI, you get a product that meets ATF+4 requirements while remaining compatible with previous ATF+3 and ATF+2 approvals, simplifying the transition when upgrading the transmission.
