2017-10-10

Description:

  • The fault code P0747 indicates that the pressure control solenoid 'A' is stuck in the On position. This may cause the transmission to shift harshly or not shift at all, and can potentially cause damage to the transmission.

Possible Symptoms:

  • Harsh or delayed shifting

  • Transmission slipping or not shifting at all

  • Illuminated check engine light

  • Overheating transmission

  • Decreased fuel efficiency

Possible Causes:

  • Failed pressure control solenoid 'A'

  • Faulty wiring or connections in the circuit

  • Corroded or damaged transmission fluid lines

  • Low or dirty transmission fluid

  • Failed transmission control module (TCM)

Related Parts:

  • Pressure Control Solenoid: This solenoid regulates the oil flow in the transmission. Problems with this solenoid lead to engine misfire, poor fuel economy, poor acceleration

Possible Solutions:

  • Replace the pressure control solenoid 'A'

  • Check and repair any damaged wiring or connections

  • Clean or replace any corroded or damaged transmission fluid lines

  • Change the transmission fluid and filter, and ensure it is at the correct level

  • Replace the transmission control module (TCM) if necessary
