What happened to licensed ATF clones?

I wonder what the shear stability requirements are for TES-295? Phillips says it is "high" resistance, likely due to a relative lack of VII.

This is why I use Mercon V (M1 ATF) in my vehicles with Dex III requirements:

Edit: Mercon and Dex III were, basically, interchangeable in the 90's.

IMO Valvoline's argument that dex III shears down so their AMM fluid will at some point meet the spec of used dex III is ludicrous and totally misleading but hey if people want to buy that crap argument that's their business.

Why is it ludicrous? It is exactly what GM said about the licensing specification.

And shearing isn't about the base oil it is about the amount of VII in the ATF. No base oil shears.


Of course it ludicrous its like saying use 0w20 because at some point in time the 5w30 will shear down and it will be the same. Its crap man and we both know it.
Nuff said.

More like 16 grade.

No surprise here.

Again

The truth is all DEX III fluids sheared into the 6.0cst range within 10K miles of use.

You can get the old Dex III spec if a fluid meets Allison TES-389.
Or Dex III with the PAO base - TES-295.
Pick either one if you want more viscosity than DexVI.
