After a 6 hour drive, my 2012 Nissan Sentra 4 Cyl would not go past 40 MPH. Pedal to the floor and the RPMs would not go past 2500-3000. After resting the car for 20 min or so, everything was back to normal. I got the following codes: P0725, U1000, U1002, P1722, P0744, P1701. What repairs do you think are needed?

All the codes are related to the transmission and communication of the Transmission Control Module (TCM) and Engine Control Module (ECM).

Looks like at some point the TCM lost communication with the ECM. Unfortunately, there are many reasons why that could happen. Start by checking the battery terminals and battery voltage. If all check OK, then clear the codes, drive and check what code comes back first.
