I stand corrected. Not flown the 737 but even the 747-100 did auto go-arounds so assumed that more modern aircraft would too.
Back in my box now.
Just to be clear there's no need to get back in your box, you're not far wrong.
If you opt to fly a coupled approach in a
genuinely modern Boeing product such as the rip roaring up to date 747-400
or the 777 you will, by default, be flying a multi channel approach. If you hit the TOGA switches with the Autopilot engaged you
will do an automatic go-around.If TOGA is pressed the power should run up to Go around power, the aircraft will pitch to fly a 2000' ROC and the aircraft will hold the current ground track..the autopilot certainly shouldn't disengage.
