RPM flux between 40-50mph

I truck started fluxing the rpm by about 100-200 between 40 and 50 mph. I know that is a shift point and I believe it is the torque converter locking and unlocking. What would cause this??? I do have the edge juice w/attitude and it does this with it on or off.

Reset your APPS.

It it a pretty common issue...the converter is locking and unlocking.

How do I reset the APPS?? Just unplug a cannon plug and reconnect or the battery??? Thanks for the info.
