my local repair guru who has decades of VW experience recommends a couple cups of a seafoam product in the transmission to make shifting smoother. I just recently replace the transmission in an 08 needless to say they’re difficult to fine I understand they run hot and the fluid off and turns dark colored due to the dual clutch (heat)

His theory is that the seafoam product thins out the transmission fluid a bit and allows for better shifts this is based on his experience as owning a Volkswagen repair shop I’m just wondering if anyone else has heard of this method?
