The 2006 Infiniti G35 would crank but not start after a transmission replacement. I found 2 transmission codes. U1000 which is a CAN bus code and P1815 which is the manual shifting code. It is an automatic transmission with fairly low mileage.

Does anyone know if it may need a TCM reprogram or why it doesn't start after the auto trans replacement?

The CANBus error is key here. Something is shorted, broken or not connected.

The suspect electrical components are:

  • Manual Mode Switch Circuit
  • AT Shift Selector Assembly
  • Wire Harness and Connectors between components
