the tranny module possibly, is the computer if you like that essentially selects the gear and regulates the kickdown etc, you may find some of the gear functions aren't working or ereatic gear changing due to this module malfunctioning, i would certainly say this is not a job for the home mechanic and its best to be sorted professionally. I am known on here as "numb nuts" so if I am wrong I am sure someone with more experience will be happy to help out.
