Hi simpletim,
You need to get a scan done to find out what is causing the CEL to show. As to the gears not shifting, check if transmission fluid is level is correct.
If fluid level is correct, you migh have a failing trans that needs a rebuild or replacement or the TCM might be faulty.
Get the CEL checked first, it might be related to the trans not working.
