There's plenty of "what ifs" floating around at this point, but the fact that the transmission was whining and full of metal is pretty damning.You have no way of knowing that. What we do know is that one product was specifically designed with this particular transmission in mind. The other is a compromise designed specifically to be close enough for no less than a dozen other fluids that themselves are incompatible with this transmission. That makes the Amsoil inferior in most modern transmissions.
Regardless of the outcome here, Amsoil is a company from the good ol' days running a universal fluid model. That's fine for oil and older transmissions, not fine for modern transmissions. If the transmission is marginal spec and the fluid is marginal spec, those two lines crossing ends up like OP. Maybe factory fluid would have saved it and maybe it was doomed, but we'll never know because they didn't help things when they added a product that was not correct for the transmission.
