The transmission is computer controlled by the same computer system that runs the engine. It will upshift if needed on a downhill to prevent damage to the engine. Just let it spin away and nothing bad will happen, using the brakes as needed to keep your speed where you want. The V10 does sound like it may be self-destructing, but it isn't and it can run all day at pretty high RPMs without trouble.
Frankly, on a modern vehicle with an automatic transmission, the tachometer is pretty much just eye candy. I guess it is handy to tell if the engine is running or not when you first start it if there's a lot of background noise around (and the plethora of idiot lights turning off don't clue you in). Other than that, I think it's best to ignore it and let the engine controls do their thing as programmed by the manufacturer. Typically, it's not even possible to damage a modern automatic by shifting it into first/low gear at highway speeds; the transmission just won't downshift if doing so would overspeed the engine.
