It's normal. The blue "COOL!" light goes out a bit before the transmission upshifts to high. Someone recently posted the coolant temperatures the ECU looks for, something close to 130°F to turn out the COOL! light, and close to 140° to let the tranny shift normally IIRC. Don't bug the service people, they can't change it for you.
