Motorcraft MERCON LV Automatic Transmission Fluid (ATF) 12 Quart Case vs Castrol Transmax ATF High Mileage Transmission Fluid

No sources that perform objective hands-on testing have deemed the Motorcraft MERCON LV Automatic Transmission Fluid (ATF) 12 Quart Case worthy of being included in their Transmission Fluid roundups, which typically isn't a good sign.

Taking a look at the Castrol Transmax ATF High Mileage Transmission Fluid, we found that it hasn't managed to perform well enough to earn a spot in any Transmission Fluid roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.

As a last step, we wanted to do a head-to-head Motorcraft MERCON LV Automatic Transmission Fluid (ATF) 12 Quart Case vs. Castrol Transmax ATF High Mileage Transmission Fluid comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
