The P2754 fault code indicates that there is an issue with the transmission fluid cooler control circuit, specifically that the circuit's voltage level is lower than expected. This can affect the transmission's ability to maintain optimal temperatures, potentially leading to overheating and poor performance.

What are the symptoms of the P2754 code?

You might experience several symptoms if your vehicle triggers the P2754 code, such as:

• Overheating of the transmission fluid.
• Delayed or harsh shifting of the transmission.
• Unusual noises coming from the transmission area.
• Warning lights on the dashboard, particularly the check engine light.

What causes the P2754 code?

Common causes of the P2754 code include:

• Faulty transmission fluid temperature sensor.
• Damaged or corroded wiring or connectors in the cooler control circuit.
• A malfunctioning transmission control module (TCM).
• Issues with the transmission cooler itself, such as blockages or leaks.

How to fix P2754?

To address the P2754 fault code, you can take the following steps:

• Inspect the wiring and connectors for any signs of damage or corrosion and repair as necessary.
• Test the transmission fluid temperature sensor and replace it if it's found to be faulty.
• Use a professional scanner to check for any related codes that may point to issues within the TCM or other transmission components.
• Flush and replace the transmission fluid if it is found to be dirty or contaminated.
