What Does P2753 Mean?
The transmission control module has detected an electrical fault in the transmission fluid cooler control circuit. This circuit controls an active cooling system (typically a solenoid valve or pump) that regulates transmission fluid temperature through an external cooler.
Common Causes
35%
Faulty transmission fluid cooler control solenoid or valve
25%
Open circuit in cooler control wiring harness
20%
Damaged or corroded connector at cooler control component
15%
Blown fuse or failed relay in cooler control circuit
5%
Failed transmission control module output driver
Diagnostic Steps
1
Step 1: Locate and inspect transmission fluid cooler control solenoid/valve and connector
2
Step 2: Check relevant fuses and relays in the transmission cooler control circuit
3
Step 3: Test voltage supply to cooler control component with ignition on
4
Step 4: Measure resistance of cooler control solenoid and compare to specifications
5
Step 5: Command cooler operation with scan tool and verify component activation
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The transmission control module has detected an electrical fault in the transmission fluid cooler control circuit. This circuit controls an active cooling system (typically a solenoid valve or pump) that regulates transmission fluid temperature through an external cooler.
The most common cause of P2753 (Transmission Fluid Cooler Control Circuit/Open) is: Faulty transmission fluid cooler control solenoid or valve
Typical repair costs for P2753 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transmission may overheat during heavy loads or towing. Avoid prolonged highway driving, towing, or stop-and-go traffic until repaired to prevent transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2753 to identify the root cause.
