Best Autobox Fluid


CCCUK Member
As title says, what do people recommend for topping up/replacing automatic transmission gearbox fluid? Ideally hoping to purchase locally!
I have a 72 350, with standard 3 speed box.

I recently changed (most of) the trans fluid and went for some Castrol Dexron II equivalent from Opie Oils. Dexron II was the recommendation of GM, but that has now been replaced, first with IIE and then III. But, apparently, Dexron VI is a suitable replacement and can be used.

My only proviso was that I wanted to use a "known" brand, as opposed to something form one of the supermarkets or auto stores.
