Inspect the connection at the encoder motor and make sure it isnt corroded or damaged as well as no terminals are spread open and damaged needing replaced.I have seen this cause this type of fault here before.One of the biggest issues on this model I have seen is the encoder will short out and damage the TCCM.If the TCCM is replaced before the encoder is replaced the faulty encoder will damage the new TCCM right away.So if you replaced the TCCM before you replaced the encoder there is a chance that the new TCCM is damaged needing replaced again now that the encoder motor has been replaced.

That is great to hear you found an issue here.I suspect this will correct the issue here.I have seen the wrong installed before that causes issues here.If your encoder motor on the transfer case is new once your new module gets here you should be good to go.
