Burla, Thank you for contacting Red Line Oil, the TBN and TAN for the D4ATF and C+ATF are 1.29 The calcium in the D4ATF and C+ATF are 255ppm, the D6ATF is 185. The calcium in the ATF's isn't TBN calcium but is detergent calcium. The only increase of the acid number in an ATF would occur due to oxidation as combustion by products are not present, which shouldn't be an issue with a good synthetic. Regards, Dave Granquist

I was under the assumption that D6 was a thinner version of D4....apparently the differences are greater than that.
