I've been noticing for the last few months that while running at least 40mph the trans will either drop 200 rpm or go up 200rpm. Not constant, but once I get above 65 it stops. I replaced the torque converter last summer, so I don't think that would have anything to do with it. Almost feels like it's dropping down a gear then going back up. But it's only that little bit. Anyone have an idea what the cause might be? Or maybe I don't want to know? I've been good to this truck and I'm hoping it's not getting ready to take a dump on me. Thanks
