The P2738 fault code indicates a fault in the Pressure Control Solenoid F Control Circuit in the vehicle. This solenoid is responsible for regulating the hydraulic pressure in the transmission, which is crucial for smooth shifting and overall transmission performance. When the control circuit shows a low voltage or resistance, it can lead to improper transmission operation.

What are the symptoms of the P2738 code?

Symptoms associated with P2738 may include:

• Harsh or erratic shifting
• Slipping transmission
• Overheating of the transmission
• Check Engine Light illuminated
• Reduced fuel efficiency
• Unresponsive acceleration

What causes the P2738 code?

Common causes for the P2738 fault code include:

• Damaged or frayed wiring in the control circuit
• Defective Pressure Control Solenoid F
• Poor electrical connections or corrosion
• Transmission fluid leaks, affecting pressure levels
• Faulty transmission control module (TCM)
• Contaminated or low transmission fluid levels

How to fix P2738?

To resolve the P2738 fault code, the following steps are recommended:

• Inspect the wiring and connector for the Pressure Control Solenoid F for any signs of damage or corrosion.
• Replace or repair any damaged wiring or connections.
• Test the Pressure Control Solenoid F with a multimeter to check its operation. If faulty, replace it.
• Ensure that the transmission fluid is at the correct level and is clean.
• Clear the fault codes and take the vehicle for a test drive to confirm that the issue has been resolved.
