My car has 137000 miles.
My car has an automatic transmission.

Hi there. Check the harness to the transmission and see if there is power. If there is no power, then check the harness for any broken wires or burned wires that could keep the transmission from working. If you had to short out a sensor to make it work, then check the circuit that the sensor is plugged into for proper continuity. Be very careful when touching wires to other circuits for it could short out he computer. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the throttle position issue.
