I think an explanatory video is a good idea. I don't mind at all that it is a 525.
What gets me is that after warning people to read the label on the pan, and to use the correct fluid (both great recommendations), a generic Redline D4 ATF is shown in the photo. At least use the correct fluid, it does matter. As a side note, I wonder why Redline advertises that their D4 fluid is good for extended drain intervals.
Also, the thread recommends 30,000 miles for ATF fluid changes. The PDF recommends 60,000 miles.
A final point, in the thread it is posted that changing fluid at higher mileage is always a good idea, that the only problems experienced after a fluid change are due to transmissions which were already failing. This is not at all true and could cost customers a lot of money. Transmissions that function perfectly have in many cases failed after a fluid change. I think you can link that to the high detergent levels in the new fluid, which clean out the transmission and move crud that wasn't hurting anything to a place where it does hurt something. If you do fluid changes soon and often, for example every 30,000 miles, then that risk is greatly reduced. Then you just have to worry about the cost effectivenss of changing fluid every 30,000 miles or so, and whether it will in fact have any impact on transmission life.
