Reset tcm?

2011 Chevy malibu 2.4 liter flex fuel 6 speed automatic transmission. I wanna reset the adaptive transmission in my car due to shift flares randomly. Usually in stop and go traffic at lights. Would disconnecting battery overnight do that? I've tried for 10 minutes to 3 hours and nothing. Think all the power isn't out of system. Thoughts?

    Take both battery cables off the battery and hold them together for one minute.

    Many people confuse shift flares for a bad tranny.

      If my transmission was bad. It would do it every shift I feel. Thoughts?

    You need a dealer level scanner.  See a mechanic.
