Your problem is most likely in the Torque Converter Connection circuit. The Torque converter has a “lock-up” feature that connects the transmission directly to the engine to reduce gas mileage. If the “lock-up” does not let go when you stop, it is like a manual transmission stopping without the clutch. The problem is in the switch or the circuit. You will need to take it to someone who can diagnose the electrical issue. Good luck.
