It is possible the TCM or a poor ground circuit is causing the problem. However TCM seldom produces 2 codes that are similar and I would bank it more on the ground circuit or a slip in the transmission.

The three components common to both circuits are the OD clutch, input and output sensors. How was the valve body checked?
