Order of inspection
P0746 Pressure Control Solenoid A Performance or Stuck Off High
The P0746 code means the solenoid that regulates transmission pressure is not controlling the way it should, or it is stuck in one position. The result is harsh shifts or slipping, depending on whether the pressure is too high or too low. The condition of the fluid is the first thing to check in almost every case.
