No, there is no core charge on this item. You can keep or dispose of your old module without needing to send it back to us, saving you time and money.
How do I know if my TCM is the problem?
Common signs include erratic shifting, getting stuck in one gear (limp mode), and specific diagnostic codes like P0700.

This 2007-2008 Yukon XL 1500 transmission control module is the most common solution for these issues.
