EXCELLENT RATING ON

Cost of diagnosing the P2753 code

P2753 is a diagnostic trouble code (DTC) for "Transmission Fluid Cooler Circuit Low". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $154.99 . Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $50.0 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.

P2753 code definition

A P2753 trouble code (sometimes registered as P2754) registers a malfunction in the automatic transmission cooler control circuit, picked up by the PCM. Other supporting modules could include:

  • Transmission control module
  • Body control module
  • Antilock brake control module
  • Instrument panel control module
  • Fuel injection control module
  • Turbo control module
  • Antitheft module
  • Cruise control module
  • Traction control module
  • Climate control module
  • Proximity alert module

What a P2753 code means

If an error is registered in the automatic transmission cooler control circuit, a trouble code will be stored and the malfunction indicator lamp (MIL) will illuminate. Some models may require as many as 8 drive cycles with the problem before the MIL will illuminate, while others might activate it after the initial failure.

Symptoms of P2753 code

  • Stiff, erratic shifting or “gear hunting”
  • Stored trouble code
  • MIL illuminated or Check Engine Light

If the code is stored but the MIL has not illuminated, the code may still show up on a code reader as “pending”

Causes of P2753 code

Diagnosis of P2753 code

Many vehicles feature an electronically controlled valve in the automatic transmission cooler lines. This valve helps regulate the flow of fluid to the cooler while operating. The valve helps the transmission fluid rise to normal operating temperature more quickly. It is controlled by the PCM or a similar controller, which relies on inputs from sensors in the controller area network (CAN). CANs are a communications bus that enables a chain of controllers to work with each other without a single host computer.

The CAN comprises an information-sharing pipeline through a complex connection of wiring harnesses and sensors, controlling practically every electrical function on a vehicle. Control modules rely on input data from a number of sensors and pass these signals on to system components and other control sub-modules.

For a correct diagnosis, you will need an OBD-II scanner/code reader and a digital volt/ohmmeter.

  • Start with a visual check of all wiring and connectors, and repair/replace any corroded, shorted, damaged or disconnected wiring, connectors and components. Retest system after repairs. If all wiring and connectors, including fuses, check out in normal working order, hook up the code reader to the diagnostic connector. Record all stored codes and freeze frame data.

  • Clear codes and test drive the vehicle to see if codes return. If not, the condition may be an intermittent that could possibly be left to worsen before a proper diagnosis can be done.

A P2753 code can be very difficult to diagnose and repair, due to the amount of circuitry and network connections involved. An experienced tech with a specialized scanner, such as an Autohex or Tech II, might be able to narrow down the problem more quickly than a tech with a basic code reader and digital volt/ohmmeter. Using a volt/ohmmeter might involve testing hundreds or thousands of circuits individually, and one misplaced probe can wipe out a chain of expensive modules and neutralize the vehicle’s memory, requiring a complete reprogramming.

How to repair a P2753 code

It’s important to use a memory saving device, in case the system experiences a meltdown.

  • Specialized CAN diagnostic scanners can show pin values and control module condition, and can accurately diagnose problems in computers and circuits in real-time, while the vehicle is being operated.

  • Locate all control modules (sometimes as many as 18) and inspect for any loose wires, corrosion of other problems.

  • Check control module ground circuits for continuity with battery ground. Codes like P2753 are often caused by grounding issues. An auxiliary ground cable is recommended. Check for any ground cables, straps or wires left dangling after recent engine or transmission work.

  • Check for any loose or corroded connectors that could increase circuit resistance and cause a code to be stored. A CAN bus system wiring diagram and pin out value chart can be handy – use the digital volt/ohmmeter to check continuity between individual controllers.
