The speedo isn't working because the TCM isn't working.
Both of those codes are TCM communication faults. I would be looking at wires and fuses.
The connector on the bottom of the trans passenger side is the vehicle speed sensor. It is vulnerable to varmints and running over things.
Fuse #43 under hood.
You might try disconnect/reconnect the TCM connector. (disconnect negative cable on battery first).
Is the "Darth Vader" plastic hood still covering the ECM & TCM? Any chance that somebody touched the TCM with a hot wire?
