Zf Traxon Service Manual <HD – UHD>

: Uses TE-ML 02 grade oil. Oil capacities vary by model (e.g., 12.5L to 24.5L depending on the presence of an Intarder).

The manual stresses: "Only use ZF Fluids." Non-approved gear oil (e.g., generic 80W-90) will corrode the internal copper bus bars and shift rails, causing intermittent electrical faults. zf traxon service manual
