I was driving down the highway, come around a turn, bam a fairly large boulder. Of course I can't swerve or I'll go in the river. So my transmission oil pan takes the brunt of my unfortunate luck. Leaks out all of that Honda goodness along the highway. Needless to say I needed to fix that and get it filled back up asap. Look online. Sweet baby Jesus. Even the company that makes the oil for Honda is still almost triple what this was. So I took a chance. Mainly because I'm not going to act like I know the intricacies of the differences between each proprietary oil. However. I know in order to meet certain standards they have to at the very least get to a minimum point to list themselves at what they are saying. So far it's worked out just fine. Will I know if there was a difference? Nope. Will others say you should have gone with the name stuff. Probably. But I do know neither of us really know whether or not it would have made any difference at all. And at the end of the day I got what I needed at a fraction for all 5 I would have of just one of the name brand. So that's ok with me.

Great transmission fluid for Euro cars

I've always put this in my 2008 Mini Cooper S automatic and its one of the best transmission fluid out there. I bought a used transmission and filled it with 7 quarts of this Castrol 4th gear was slipping a little but after 600 plus miles of driving slipping is now gone.! I will still drain and fill after 1k miles since I put in a used transmission . I TRUST CASTROL transmission fluid and Full Synthetic oil for my cars!

Aside from Valvoline automatic transmission fluid being an alternative option, the Castrol Transmax was also recommended by a mechanic. I found that this works exceptionally well in cold weather conditions and since I was seeing 20 degree temperatures in the day's average I chose it for my Honda Ridgeline Sport. After driving my Honda 3 days in frigid temps and winter mix conditions, I found the shifting during acceleration was smoother and fuel efficiency improved. The Protection from wear and Castrol's known reliability were known advantages and I couldn't be happier with the sale price for the gallon.
