not sure about the instrument cluster/guages... but that setting on your tranny should be a switch between norm or pwr... basically (from my understanding of it), it's electronically controlled to allow a different band of RPMs for the gears... dunno if it's thru changing shift points, gear ratios, or what... but I don't think it's a switch to manual... those kinda trannies didn't become popular till the turn of the century (as far as I know).
