That doesn't sound right. It sounds like it might be correct on an Airbus, but not a Boeing. On a 737, yoke movement mechanically controls the elevator and the trim system mechanically (and with a motor to help) controls the stabilizer. There is no connection between the yoke and the stabilizer on a Boeing. Does that make sense?
It's not just that the trim wheels don't work when the yoke (not yolk) is pulled, but that it can require too much torque to move them -- it's a purely mechanical connection with the motor off -- when the elevator is deflected in opposition to the stabilizer.
