I have an automatic transmission, with overdrive. After about an hour of driving, when I come to a stop. The car will not move after stepping on the gas pedal. I have to switch the gear down to 1st.gear, and slowly work my way up the gears until I’m and D for drive. The car feels sluggish, no power . I have to switch the car off. And wait awhile so the system can go back to normal. Also the overdrive light flashes when the car is acting up..

When driving & come 2 stop when accelerate very weak then becomes mostly sluggish take off
