Here is a ground schematic. I can get you a higher resolution.

Thank you

Ok found a buddy who has a Snap-On scan tool. No current codes in the TCCM but under History C0327 and C0379 come up. 327 with a few quick checks seems to be encoder motor? I am guessing since this is the 3rd one that has been put on this truck that is not issue so maybe a wire or harness that causes this code? Do these codes coming up together help identify the issue? Anyway going to do some investigating on my next time off in a few weeks. thanks for any information on this.

Note that an encoder motor swap (for NBS) does NOT require any programming. If the TCCM is replaced it WILL require programming unless it's the Dorman replacement. The OE TCCM may also benefit from a calibration (programming) update if there is one available.
