Coastal is basically the "Autozone" brand IIRC. The cost is equal or a little lower than the name brands. Getting it in the gallon container saves a little as well.
I know that when Jr's3800 and I spoke, my plans were to get a higher cost fluid and after speaking..he had me buying the Coastal. When I compared it to the Advance store brand, it was a little heavier aka slightly thicker when cold.
It'* all my Intense built transmission has ever run.
