737-800 trim wheel

Sorry if this is a stupid question, and it is slightly off topic:

I don't fly the 737, but have done 16 hours in a 737-300 simulator. I remember being initially scared stupid by the trim wheel spinning round, and noise it made! (Got used to it though) My aircraft doesn't have a trim wheel, so you don't get any sense of it trimming, other than by looking at the stab trim position indicator.

Does the NG also have a noisy trim wheel, and if so, would it not have been trimming back as it tried to stay on the GS? If so, would that not have been thought unusual by the crew?

Along with all the basic airmanship that goes with flying, including the absolutely critical instrument scan, I am always looking at the EPR commanded during descent - 1.18 is normally on the ball depending on weight & wind component, and anything significantly away from that would have me examining the flight path critically to ascertain why, before satsifying myself that the commanded EPR (or lack of) is correct for that phase of flight.

DW.
