Truck manual transmission: often API GL-4 or GL-5 (SAE 80W-90, 85W-140). ZF gearboxes require ZF TE-ML (e.g. 05L, 07C) – do not use universal oils without release. Filling quantities 10–25 litres depending on the gearbox.

For automatic (Allison, ZF converter): Use manufacturer's ATF. Avoid mixing different specifications.
