Low rev when idle 2010 Liberty

2010 Liberty 2.5i Premium (Sat) - vehicle used to stall when idling prior to torque converter being replaced. Car no longer stalls however when idling,
particularly when A/C is on, the car will occasionally drop in revs to the point where there is a shudder (pre-stall) for approx 2-5secs then the revs will pick back up. This is repeated about every 15-25secs.
Is there a way to reconfigure transmission computer system to not drop in revs?
What would be causing this issue?
Thanks
