Just wondering if there is a preset mileage when the service engine soon light will automatically come and if so, for what reason (I.e transmission service, specific engine/drive train service, ext.) if not, what would be primary potential for reason of coming on.

There are many things that can turn it on. Have the computer scanned to identify where the problem is coming from. Most parts stores will do it for free.
