Welcome to 2CarPros.
If it worked prior to the repair, I going to say there is a good chance it is. There is a vehicle speed sensor on the transmission that could have been damaged, left loose, disconnected, or the wiring may have accidentally been damaged.
I attached a picture of the transmission. Going to each front wheel is an axle. Near where the axle attaches to the transmission, you will see a sensor. Make sure the wire is attached and tight. It should be on the driver's side of the vehicle.
Let me know what you find.
