Hello , my Toyota dealer Service dept. added a used car kit to my 2019 CHR engine when puchased . This included VP093 Transmission Conditioner along with others (Vp004,806221treat) . I feel this may have lead to a Humming sound from the Transmission .

I wanted to clarify if this practice is okay with Toyota Engineering before trying to flush Trans.Fluid .

Vehicle runs fine with exception of humming sound (more noticeable on sport) , has 35K miles. THANKS SO MUCH FOR THE SUPPORT, I BELIVE TOYOTA IS A GREAT MFGco.
