Symptoms

  • •Check engine light illuminated
  • •Harsh or erratic shifting
  • •Delayed engagement when shifting from park to drive
  • •Transmission slipping or failing to shift
  • •Poor acceleration performance

Diagnostic Steps

  1. 1Scan the vehicle's computer using an OBD-II scanner to confirm the P0750 code and check for any additional codes.
  2. 2Inspect the transmission fluid level and condition; low or dirty fluid can cause shifting issues.
  3. 3Visually inspect the wiring and connectors leading to the shift solenoid for any signs of damage or corrosion.
  4. 4Test the transmission shift solenoid 'A' using a multimeter to check for proper resistance and functionality.
  5. 5Check the vehicle's battery voltage and ensure it is within the specified range (typically 12.4 to 14.7 volts) as low voltage can affect solenoid operation.
