Hi xraytommy93
This is your code
DTC 639 indicates frequency or voltage of the TSS/OSS is insufficient to the Powertrain Control Module (PCM).
The sensor is located on the drivers side of the trans, just above and back from the shift linkage/range sensor. It has a two pin connector and a single bolt holding it in the case.
The resistance of that sensor is supposed to be between 450 and 750 ohms.
Hope this helps you
