How to Fix Error Code P1245

  1. Check engine light and scan for codes

    Ensure the vehicle is parked on level ground with the parking brake engaged before beginning any diagnostic work.
  2. Inspect transmission fluid level and condition

    Check fluid with engine running and transmission in park. Hot transmission fluid can cause burns - use caution.
  3. Check electrical connections to transmission

    Disconnect the negative battery cable before working on electrical connections to prevent short circuits.
  4. Test solenoid resistance with multimeter

  5. Check transmission control module power and ground

  6. Inspect transmission valve body (if accessible)

    This step requires transmission fluid replacement and proper torque specifications. Consider professional service if unfamiliar with transmission work.
  7. Clear codes and test drive
