@ymb1 Found this on pprune: “ The term 'Mach Trim' is normally associated with conventional flight control systems which have to provide a feel force feedback to the pilot.
With increasing Mach No the aircraft might suffer reducing stickforce-speed relationship which defines stability; Mach Trim applies a corrective trim offset to mask the effects of this change.”

The Boeing 737 was originally designed in the 1960's and flew into the 1980's before a major redesign (the 737-700, -800, and -900 models) was implemented.
Coming up in a few years will be the next major revamp of the line as the 737-Max series (737-7, 737-8, and 737-9).
What major changes hav...
