2008 Kia Sorento with 40K miles. Auto Transmission. I started it today and it was stuck in 2nd gear and also the backup lights would not come on when I put it into reverse. I parked, turned off the engine, checked the trans fluid, which was fine. Started it again and suddenly it drives perfect and the reverse lights come on as well.
What would cause the transmission to get stuck in 2nd gear and the reverse lights not to work, then be fine the next time I start the car?
Any help will be much appreciated,
