[Rio 01]

New to forum with a question
My son's Rio about a month ago flipped several codes dealing with the transmission, P0740 and a couple more dealing with the tourqe converter clutch and gears. I replaced the filter, fluid and flushed it out real good and it worked great, then yesterday the light came back on and reverse started messing up. Could it be the selonoid and if it is where exactly is it?

Any help would be greatly appreciated

Thanks

Pulled the codes and am only getting P0740, torque clutch converter malfunction, could replacing the solenoide fix it or?

Thanks

Did you get this fixed. I would replace the Torque Converter. Your torque converter clutch in actually inside the torque converter keeping the stator from going into a free spin during acceleration. What were the other codes that came up, how is the trans acting?

I have a 2006 optima, the check engine light comes on during heavy acceleration. I forget the exact code but it refers to the torque converter circuit. I get vibration on medium to heavy acceleration
