Hi guys I want to change my gearbox oil but don’t know the colour of the tag on the gearbox. So does anyone know what grade a manual 2003 3.0 would take please.

GL5 can eat certain metals in older gearboxes.

..although, just to confuse matters, some of the GL5 fluids are also GL4 compatible like the Millers TRX 75W80... https://www.ebay.co.uk/itm/Millers-Oil- ... 2512134690

In an older box, I would put GL4 in, better safe than brassic :)
