Only way is if there happens to be the IMS Solution installed. There is a register for that setup, other than that, the trans has to be pulled. If it has been changed, you might be able to ID by the flange cover, but really, the only way to tell is to take the whole thing apart. Clutch, RMS and what not are the things to do while there. At that mileage, tough call what to do. If not a tip (auto) and the clutch is good, it is unlikely the clutch is original, and most people at least inspect the IMS for issues, and usually replace at the time.
Another thing that is possibly tell tale, and well documented, is to inspect your oil filter for metal, and get a run down on cam deviation with a purchased durametric, or take it to a dealer/shop to do a full engine diagnostics.
