Has anyone installed the Sonnax valve kit 84754-43k? I looked up the instructions on Sonnax website and it mentions this one part about using a drill bit to bore out the end of one of the bores but it is very vague. Could anyone help clear up how this is installed. The whole reason I'm rebuilding the transmission is due to TCC shudder. So if this kit will help id like to install it. Plus I already have it.
