I’ll also add that you’ll want to visually make sure your virtual on-screen throttles are lined up before hitting the THR button on the MCP. If they’re not, then they seem to stay uneven with A/T on. My Boeing TM Throttle Quadrant has slightly-different hardware-level response curves for levers 2 & 3, so even if they are physically even, they are a bit askew in the plane. But the new Throttle Lockout feature prevents the highly-asymmetric thrust conditions that have been widely reported.
