Here, we analyzed three ATF's.

where Valvoline MaxLife does show it has an elevated Anti-Wear package.
Is there a similar analyze for Toyota WS?
The main focus of the Analysis and comparison was to show that even though certain fluids claim coverage or, similar operational characteristics, the analysis showed two of the chemistries to be highly disparate when compared to the Original Honda DW-1 and to warn prospective buyers that the chemistry of original Honda DW-1 was incompatible with modern Step-Shift automatics and should not be used in modern Step-Shift automatic transmissions. Each analyses would cost upwards of $500.00 if done in other than a university chemistry lab.
When formulating or qualifying ATF formulations, a multitude of bench tests are performed and then an actual set of multi-hour dyno tests are run on two or more transmissons to determine the friction characteristics of the fluids.
The transmissions are then torn down to compare new part dimensions to the tested transmission parts dimensions for wear. In some cases the weights of each of the parts are compared to determine mass loss.
So I hope you can appreciate why neither project farm has the qualifications to determine anything about ATF, nor does a simple $28 analysis determine friction coefficients, quality, or compatibility across transmission makes.
