I have not had time to drive the car for about 5 months. I went to the storage area checked the levels on various things started the car and went for a drive. When in overdrive the car will some times stall around 40-45 mph sometimes i will be almost to a stop and it will be running again. 1 time i took the car out of gear put it in neutral and the car was running again. I was wondering if i disconnected the wire to the coil on the overdrive circuit and it stopped then it would tell me its in the od Circuit. It also seems to happen when its around 150 to 160 degrees.
