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.
