So you won't notice that you can't maintain level flight?
If you can't pull up because the yoke is too heavy you have to use the trim switches.
Or maybe you would not use the trim switches because you are not running a checklist? Seriously?
If the trim switches don't work it's obvious you need to do the Runaway Stabiliser checklist and use manual trim.
You don't even need a checklist for that it's more like switching the autopilot off and flying by hand.
