cost labor and part to change out a automatic trans.shifter cable.

Hello, Unfortunately, we do not have an estimate for this service in our estimator tool, but considering R&R plus adjustment of the new cable, three hours may be right. Here is what I recommend: get a second opinion. Any time there are concerns of fair treatment, whether they are obviously unfounded, borderline acceptable, or completely accurate, I always recommend a second opinion. You may find the price lower or higher, but if the price is fairly close, I would stick with the dealership.
