When I asked about this my tech sources told me it is possible. Going down a hill with the gearbox in manual shift mode. The tranny will not upshift and the downgrade if steep enough can allow the engine to overspeed.

Note this can also be a source of overrevs for a manual equipped car as well.

I guess I don't need to worry about it since I live in flat Florida.
