Where is the transmission control module on a 2001 Ford Explorer sport trac?

The Transmission Control Module (TCM) on a 2001 Ford Explorer Sport Trac is typically located within the transmission itself. Unlike some vehicles where the TCM is a separate unit under the dash or elsewhere, in this model it's an integral part of the transmission assembly. This means you won't find a separate box labeled "TCM." To access it, you'd need to remove or at least partially disassemble the transmission. This is a job best left to a professional mechanic.
