OP, I see now that you mentioned in an earlier post that your SHO is not equipped with the Performance Package.
Only the PP PTU has a temp sensor, right?
So, it is likely that there wasn't any aux cooling to save the bearings, and no sensor to trip a dummy light.
@SHOdded, there IS a write up out there for non PP cars, right?
Seems more and more like servicing the PTU is becoming an imperative maintenance item, particularly on non PP (or pre 13 PP?) equipped SHOs.
