Computer or torque converter fault can cause Check Engine Light on Isuzu Oasis

There is an issue where the transmission can have a torque converter problem, or the computer monitoring the torque converter can misinterpret the information, and in either case this can cause the Check Engine Light (MIL) to illuminate. The problem will need to be diagnosed and depending upon what is causing the issue, the transmission will have to be repaired or the computer replaced.

problem details
After being drove 1 to 2 hours on high way at high speed, the car lost power at low speed. The engine worked strangely when stopping the car. Feel like the transmission was broken, the gear did not shift smoothly. Just had the exhaustion system except for converter replaced. After the engine turned off for a while, the car run normal again. It happened two times yesterday.
