Automatic transmission problem
Asked by edgaleyjr Dec 25, 2012 at 07:22 PM about the 2002 Hyundai Sonata V6 GLS FWD
Question type: Maintenance & Repair
My automatic transmission will jerk, the check engine light will come on, I lose 1st and 4th gear. If I turn
off the car, and restart it, the check engine will stay on, but I regain 1st and 4th gear. It only does this
occasionally, and I am wondering if it is something electronic that is the problem, or something
mechanical causing this.

I would start with the electrical. Clean and tighten the battery connections. Read the voltage of the battery with the engine running. It should be around 13.5-14.5 volts. Get the codes read and find out why the check engine light is coming on.
Same problem Hyundai fixed in 30 min , it was a sensor they wouldn't say which one (warranty) same problem though as you.
Had similar problem with my 2002 base model,replaced input and output transmission sensors.Resolved issue.
My friend has a similar problem on a Hyundai Sonata. The dealer check it out and said it is working normally because the car did not act up during the rest drive. There is a good article online titled Troubleshooting Hyundai Transmission posted on YOUCANIC, it goes over the common problems with these cars. Worth checking out.
