Human Factors
We were late arriving after departing late due to lightening [at the departure airport] that had closed the ramp and the same storms forced a routing increasing the flight time. Schedule was not an issue and we were not pushing the field to make up time. Once arrived in the area; it was VMC with 10SM visibility (actually closer to 20SM). We were cleared a visual approach approximately 16 miles from runway 33L at 6;000 feet MSL after being instructed to descend to 4;000. Pilot Flying (PF) was just a bit slow to descend out of 6;000 feet and Pilot Monitoring (PM) prompted PF to start down.The aircraft continued to be high on profile and PF called for flaps 1 and selected LVL CHG 203 knots. PM had the VOR frequency to note the 10 DME/3;000 feet restriction and was instructed to contact Tower approximately 8 NM out. While the gear was down; the PF failed to select a lower speed in the window; which caused the auto throttles to increase power; although the aircraft was already high on profile. The PM failed to notice the 203 in the speed window. PM became task saturated; resulting in PM's failure to switch to Tower while directing PF to disconnect the auto throttles; pull the nose up to get below 195 knots; in order to select flaps 15 and continue on profile.Crew was able to track flaps on speed and accomplished the Before Landing Checklist. The runway was clear and everything looked like a normal approach from 1;000 feet AGL. Once turning off of the runway; the Crew noticed they were still on Approach frequency as they switched to Ground. Ground didn't mention anything except taxi instructions to the gate.
