Assuming Maxlife ATF is $8-9/qt and OEM WS is $12-13/qt - the difference is $5/qt approx.
If you use a gallon for a drain and fill every 2 yrs (or 25,000 miles) then the cost difference is about $25 amortized over 2 yr period = is $13 per year.
Why, why not just use the OEM fluid. I think it's worth the peace of mind for 13 bucks a year.
Believe me, I know because I had a pay partially for a Honda transmission rebuild - because a "stupid" mechanic put in the non-OEM fluid (when I had specifically asked for DW-1) in my Odyssey. Paying $1500 was not fun.
