2010 Chevrolet Aveo Automatic Transmission - OBD
I had Flashing Hold Light and Engine Light. From L1 driving then it automatically goes through gears even at low revs. ODB gives the following codes P0705 and P1601 ODB dies not want to communicate with automatic transmission. I used DM820. GM workshop dealer cleared the codes but they came back but not seen Flashing Hold Light Engine light. Car still in GM warrantee but worried about them fixing it. Any suggestions on resolving the codes and auto gearbox functionality, please help!
