I recently bought a used 2006.5 Kia optima, 2.4L 4 cylinder with an automatic transmission. Currently has 93,000 miles.
2 days ago I drove from Ma to Va about 650 miles. Drove excellent and had to be getting at least 30 mpg. No problems in the drive train whatsoever.
But this morning, after about 5 minutes of driving, I was approaching a stop light and the car started to shudder as if it were about to stall out (felt just like a standard transmission car would if you went to stop with it engaged in gear and the clutch out - shuddering and RPM drop)
The light turned green before I had to stop complete, and it took off fine. Never did it again.
Brought it by Autozone and had a code P0741
Torque converter stuck off
-open or short circuit condition
-poor electrical connection
-faulty torque converter solenoid
I checked the fluid, it was full. It is a brownish color that it was before I drove across the country. I don't think it is burnt but due to be changed - fluid and filter are original to the car from the factory. Service says to change at 100 or 102k miles but I like to do it sooner to help the trans live longer, but have only had the car about 2 weeks.
Only happened once, has been perfect before and after. Goes right into gear, hot or cold, shifts perfectly smooth, plenty of power, good gas mileage, ect.
Could this just be a fluke or sign of something to come? I'd like to check into some things before having to head back home in a few days (650 miles) for a bit of self assurance.
A lot of the mileage on this car are highway, it has been back and forth from Mass to Florida several times, I bought it from the original owner whom I've known for several years.
Maybe someone else has dealt with this?
Thank you all for any input!
