What is "sonnax"?
I was informed i should do a "sonnax" upgraded main pressure valve to avoid transmission troubles in the future?
I have not been able to find more information about this...
Thanks for the advice in advance.

This is to avoid issues with the A-drum breaking due to uncommanded pressure spikes. There is an updated pressure regulator valve that replaces the original and fixes the issue.
