I need to know location of shift solenoid B in the valve body

Hello, I have to be honest, even Hyundai dealers don't mess with shift solenoids in these transmissions...having run Hyundai dealer service departments from 2008 through 2012. Have you had a diagnostic test performed? Have you used a GDS diagnostic tool to determine the operation of the shift solenoid? My concern is, if you're asking the question as you are, how could you know what to test or diagnose? If you are simply going off of a diagnostic code, it is not good enough and does not tell you what's wrong.
