From 2005 owners manual, applies up to 2008 at least:
"Notice: Spinning the tires or holding the vehicle in one place while on a hill using only the accelerator may damage the transaxle. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

If there is a malfunction with the automatic transaxle, the Malfunction Indicator Lamp (MIL), or the HOLD indicator light will turn on or flash. Have your vehicle fixed as soon as possible.

My owners manual thinks this is pretty serious! Have you ever changed the trans fluid? How long ago did you do your Tokyo-Drift-reverse-to-drive stunts?
