Technical 2006 2.0jtd gear oil type

[Gman88667733]

I purchased the recommended gear oil online from Shop4parts and went for their recommended one for my vehicle - https://www.shop4parts.co.uk/?name=store&op=Product&ProdID=72
My concern is this arrived and is GL5 spec. I am sure I read somewhere that this van needs GL4. Am I correct? Or is the oil linked above fine for my transmission?

Thanks.
