JLR JLM20238

JLR JLM20238 is an automatic transmission oil specification developed by Jaguar Land Rover for their modern ATs, including 6‑, 7‑ and 8‑speed gearboxes (e.g., ZF 8HP, JLR 9‑speed). The technical document requires stable viscosity over a wide temperature range, high wear and oxidation resistance, and precisely defined friction characteristics that ensure smooth shifting and protection of torque‑transfer components. Oil that meets JLM20238 is compatible with JLR transmission electronic control systems and contains no components that harm catalysts or DPFs, so it can be safely used in hybrid and diesel models without additional restrictions. Choosing a product marked JLM20238 guarantees compliance with OEM requirements, extended service intervals, and increased reliability of your Jaguar or Land Rover transmission.
