Problem started with a dead battery. Odd because lights will shut off to protect from battery drain, not sure why it died. Jumped and it stayed on and can be restarted. Big problem is car cannot accelerate past 20mph. Rpms don't go above 2k. It would not switch over from automatic to manual. No strange noises. Check engine light came on after awhile but cannot get it to a shop yet, wondering if there are any ideas of things I could check at home.was an out of the blue problem.
