Redline d6 atf review. Redline makes some great transmission fluids and gear oils they are one of the go to companies for automotive enthusiasts and d6 atf works just as well as ive come to expect from them. Synthetic d6 atf is suitable for use in the new dexron vi applications mercon sp or toyota ws fluids are recommended. Red line offers the widest selection of fully synthetic atf on the market today. I think atf with calcium sulfonate is the way to go. Its designed to satisfy dexron vi dexron iii dexron ii mercon sp and mercedes benz nag 2 fluids as well as api70w75w80w and gl 4 gear requirements. Reduced oxidation and lower volatility at high temperature.
Your shifting will be more consistent and smoother even over extended drain intervals. Red line atf provides a much lower cold temperature viscosity which means better performance when shifting. The d6 atf is a lower viscosity version of the d4atf and is designed for better fuel efficiency in cafe testing. Red line provides far better stability when it is compared to its petroleum counterparts. D6 atf our lowest viscosity most shear stable atf for consistent operation designed to satisfy dexron vi merconsp merconlv honda dw 1 toyota ws mercedes benz nag 2 zf lg 6 6 and 8 fluids also satisfies api 70w75w and gl 4 gear oil requirements. Beware the 20 25 a gallon atf from the big name oil companies.

Read honest and unbiased product reviews from our users. Each offer improved thermal stability maintain viscosity levels and feature lower volatility while providing the required frictional characteristics of each fluids oem style replacement. Red line d6 atf is the lowest viscosity most shear stable automatic transmission fluid for consistent operation. I guess this is why redline folks hint d4 is better fluid compared to d6 for ws application even though its a thicker fluid.
I used two bottles of this for a power steering system replacement in my infiniti g37 and am really happy with it so far.

Its group 3 which means that it is made from natural gas or dino oil with no synthetic base.
