XENUM

Chrysler ATF +4

Chrysler ATF+4 is the official transmission fluid specification developed by Stellantis for automatic gearboxes of Chrysler, Dodge, Jeep and Ram models, including 8‑ and 9‑speed transmissions, as well as older 4‑ and 6‑speed variants. The fluid must have a viscosity in the range of 6‑9 cSt at 100 °C, high thermal stability and oxidation resistance, providing a stable friction coefficient, protection against foaming and wear under high load. The specification provides compatibility with metal and polymer seals, as well as with hydraulic torque‑control systems in transmissions, without requirements for SAPS or DPF, as it is not an engine oil. ATF+4 also meets the requirements of previous approvals ATF+3 and ATF+2, allowing its safe use in older models without loss of warranty parameters. Using XENUM transmission oil marked ATF+4, technicians obtain guaranteed gearbox protection, smooth gear shifts and extended service life.
