However...you can't ignore the fact that the reason they keep having these classes is because there was/is a huge issue and they are sick of giving out warranty motors and modules together - when they well know by now it is the modules that are the culprit as much as 90% of the time.
On an X13 motor, my supply house will not accept just the module, they want to whole motor for warranty, unless something has change in the past two weeks.
