I see my auto parts store carrying Beck Arnley WS trans fluid for Toyotas. Does anyone know anything about it? Is it repackaged Toyota or Mobil fluid? I was thinking about getting it for my '07 Camry. Thanks in advance.
Beck/Arnley is just a reboxer anyway; they don't make their own stuff.
How much does this stuff cost at the store?
XOM makes Toyota's ATF's and oils, including WS.
If the Beck WS isn't substantially cheaper than the dealer, just get Maxlife.
Says who? Lubrizol/Valvoline?
How are you certain that they have thoroughly tested the fluid? Just because they recommend it does not mean that it was tested in every vehicle/transmission/software combo that specs WS.
WS is a proprietary spec that does not have a licensing program.
