The yellowing could be due to the stress from root loss during transplanting. Conifer's like this are slow to respond and this could be a gradual decline related to the root loss. This stress would have been compounded if you have not watered adequately and the tree has not been able to develop a new root system.
The good thing is that from the photo, the amount of foliage affected at this time appears minimal, so I would not say it is dying, just severely stressed.
With winter approaching you cannot expect much to happen until spring. But if mine I would deep water right now and apply a humic acid, kelp, amino acid nutrient solution like this, for root health. And again in spring when new growth starts to form.
There is an outside chance that the yellowing is due to a pest problem, like mites. To cover all the bases, I would recommend that you use a preventive spray treatment with 70% Neem Oil, now and resume in spring with at least once a month applications.
