The required spec is Dex 3 for the Omega boxes. Dex 6 should be backward compatible but you never know if there is a material in the box it'll disagree with.
Gearbox was, according to the official service schedule "sealed for life", so I'd be surprised if a main dealer changed it unless they were being very generous.
Thanks for the info
I was surprised looking at the service book
8th service (2012 @70k cambelt) ,but the skf vkma sticker shows the wrong layout for the belt
9th service (2013 @ 71,5k)plugs, air,fuel filter,brake & trans fluid
10th service (2015 @ 72k)plugs again ! fuel filter again !
11th service (2016 @75k) brake and trans fluid again
12th service late 2017 is not in book but the brake pads , discs all round, tyres,oil/filter,air filter,tyres etc etc
I think I will check the level and dip test the trans fluid to see what the condition is before i order any atf
Yes the engine oil, TC 10W-40.
OK, thanks , I'll order a tub , will do for all the astra's too
