I am soooo glad I came across this! I bought my ST in Dec and just about 1k miles in, it started this almost hesitant shifting between 3rd and 4th (comes out of gear and takes a bit before going back in) Service dept has been no help. Cleared "adaptive learning" something or other, fixed it for a couple of days. Then it was back. They "cleared the computer" and replaced some control module, but the shifting issue came right back. Let them know yesterday it wasn't fixed still and I was told about a TSB that was released so I'm taking it back Monday. Fingers crossed.
