What is a transfer case shift control module?
Transfer Case Control Module (TCCM) is the brain behind the electronically shifted 4WD systems. The TCCM processes the shift request from the dash mounted mode selector buttons, executes the shift, and verifies the shift was completed. Replace your current failing or faulty item with this direct replacement.
