Possible Symptoms:

  • Transmission slipping or not shifting properly

  • Harsh or delayed shifting

  • Reduced fuel efficiency

  • Illuminated check engine light

Possible Causes:

  • Failed shift solenoid 'E'

  • Faulty wiring or connections in the circuit

  • Loose or corroded electrical connections

  • Failed transmission control module (TCM)

  • Low transmission fluid level or poor quality fluid

Related Parts:

  • Transmission Shift Sensor: Gear Shift Sensor communicates the position the gear shifted to. Problems lead to difficulty in shifting gears

Possible Solutions:

  • Replace the shift solenoid 'E'

  • Check and repair any damaged wiring or connections

  • Tighten or clean any loose or corroded electrical connections
