Hello, my name is Bobby. Thank you for the question. This is almost always the torque converter clutch. The internal clutch fails and slips in and out like this. When you are in tow haul mode or when you hit the brakes this clutch releases automatically. It sounds like this needs to be replaced. The transmission will need to be removed to repair it. Let me know if you need more help.
