If the additives in the transmission fluid have been degraded due to oxidation, excessive heat, and/or shear, to the point where you're seeing clutch slip or shudder, you're better off doing a flush and fill with fresh ATF than trying to correct the problem with mystery additive.
I was in Vancouver recently and used Lyft several times. Judging from the stickers on the windshields, most drivers were using both Uber and Lyft to connect with passengers.

If OEMs start adding features like...
Most current EVs use low-viscosity ATF to lubricate the gearbox, but OEMs are working on developing dedicated e-drive oils that are optimized for gearbox lubrication and cooling the electric motor, while also maintaining good copper corrosion and dielectric properties. Oil producers are also...
