Truck jerks on decel/coasting

 My first problem, and post with my 2014 silverado , regular cab, 75000 miles, 4.3L auto trans. Hope I explain this well.  This just started abruptly today.

While coasting in drive, under 45 MPH, it feels like brake lightly/quickly applied, or converter lock up about every 2 seconds until stop. Very lightly, but feels harsher if brakes are applied lightly. Goes away when shifted

into neutral while coasting.  Gut feeling is torque converter locking up for unkown reason. Ideas?  Thanks, Kevin
