Hi.
As I was the one sending the ATF fluid in, I will answer that question.
This is Valvoline ATF type D. (don't know where the 'D' stands for)
I also have here at my home ATF fluid from a cheaper (European) brand but because I think it's not available everywhere I didn't send it in for the test.
Maybe I'll compare the two of them in the near future; you're probably right that different brands will give different results.
Peet.
