Or is it simply peoples opinions popping up again?

'But statistically, others would be better served by using recommended fluids' Where you have sourced those statistics from?
You are assuming that all opinions should have equal weight. The internet is an equalizer, but all posters are not the same.

You don't need to trust me. I have thirty or so years in the automotive and equipment business. Lots of experience in failure analysis, fluids, additive packages, etc. Engineering degree. Service management. And so on. But whatever, it doesn't matter. I might be a 14 year old on his Mom's computer. But, would you trust RRPhil, who has put up some great posts here, and who rebuilds transmissions for a living? If so, read this thread, especially post 50.

Professionals know these statistics. They have learned them the hard way. ZF and BMW and GM know them too. They won't give the data to you. But they will give you the conclusions based on the data. It is your decision on whether to follow these recommendations or not.

It is straightforward to link your transmission and the proper fluid. But not to solve your particular symptoms. Diagnosis would be a whole lot easier with physical inspection, to start. That is why I used the word statistically.

Have a great day.
