Hi
Here's what I think is happening, when car cold it runs on programed run settings in the computer. Once vehicle warms then it goes into operating mode where it receives input info that it uses to control timing, fuel, shifting etc. Your car has Variable Assist power steering as speed increases steering stiffens up. So on transmission is a Vehicle Speed Sensor sending speed info to ECM. Sensor is faulty effecting transmission shift. Cruise operation and steering. Have VSS checked out.
Hope this helps
