Hi,
I need more information. The TSB related to the judder should set a code. Can you explain exactly what you are experiencing?
If you look below, I listed all TSB's related to the valve body. Note they are based on codes. Also, there is a TSB related to recalibration between the TCM and the CVT transmission. If you have something different, let me know.
I will watch for your reply.

See pic below. Note: The pic below is a short portion of the TSB's related to the valve body, so let me know exactly what is happening and if the shop scanned the can-bus to check for transmission codes.
