P2757 code definition

A P2757 code refers to a detected issue in the torque converter clutch pressure control solenoid circuit.

What the P2757 code means

A P2757 code will be reported when the vehicle's onboard powertrain control module (PCM) detects an issue in the torque converter clutch pressure control solenoid circuit. This aspect of the powertrain automates the clutch application in order to optimize the engine's use of fuel.

What causes the P2757 code?

In many cases, a P2757 code occurs because the torque converter clutch pressure control solenoid circuit is faulty in some respect. Issues with the transmission's hydraulic fluid (including fluid shortage and hydraulic blockages) may also be the problem.

What are the symptoms of the P2757 code?

A P2757 code will be identified by a OBD-II code reader. Issues with the transmission, ranging from shift issues to the vehicle's engine stalling, may suggest a P2757. The P2757 is often reported alongside other transmission-related codes.

How does a mechanic diagnose the P2757 code?

A OBD-II code reader is used to identify a P2757 code. From there, a mechanic can check the vehicle's transmission pressure in order to gauge the likelihood and seriousness of a PCM-related issue. Transmission pressure ratings should read as very low in the instance of a P2757. Any findings may be compared alongside the default specifications of the vehicle's manufacturer in order to determine how serious the issue is.

Common mistakes when diagnosing the P2757 code

Simple problems with the wiring may be overlooked and blamed instead on and torque converter hardware. Fixing issues with the wiring are easier and less expensive than replacing larger hardware. With that in mind, it's recommended that problems with the wiring are ruled out before exploring more serious causes.

How serious is the P2757 code?

The severity of a P2757 may vary wildly. While the mildest cases won't have any immediate symptoms, severe torque converter clutch problems may cause the engine to stall. It is nonetheless recommended to address a P2757 issue immediately in order to prevent the situation from getting worse.

What repairs can fix the P2757 code?

Fixing any broken circuits or wiring, and cleaning and replacing transmission fluid should clear most P2757 codes. In the more serious instance of a faulty PCM, the PCM will usually need to be replaced and reprogrammed. Although not unheard of, failures in a vehicle's powertrain control module are rare. Because replacing a PCM is expensive and requires overhauling the vehicle's programming, it's recommended that other possibilities be ruled out before dealing with the PCM directly.

Additional comments for consideration regarding the P2757 code

It is common for a P2757 to come alongside other codes related to the torque converter clutch and transmission module.
