Never had the reason to kill the battery on the '02 Tahoe that the Avalanche replaced, so I'm a wee bit concerned ;)

I'd like to disconnect it to clear the PCM, but I REALLY don't want to lose the personalized settings for each driver. It took too long to set them up in the first place. My thinking is that those settings will survive. Anybody have first-hand experience on that one?
