8HP45/8HP55/8HP70 mechatronics repair/upgrade kit and technical info
Hey everyone,
By complete mistake, I found this repair kit from Sonnax for the 8HP mechatronics unit, which also includes a wealth of information on how the valve-body functions, how it fails, and the symptoms of these failures. Not necessarily great reading, but I'm hoping this post makes it easier to find this documentation in the future. https://www.sonnax.com/parts/4590-zip-kit Click "view instructions" for the pdf in question.
