P2757 Code: Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance / Stuck Off

P2757 is one of the diagnostic trouble codes (DTCs) that might show up on your scan tool when you diagnose your vehicle. There are many ways to resolve this code, but you’ll first have to identify its underlying causes to figure out the right solution. Here are some things you should know about the P2757 code.

What Does the P2757 Code Mean?

P2757 stands for “Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off.” This code applies to a variety of modern vehicles that have OBD-II.

A vehicle’s transmission control module (TCM) can register a P2757 code if it detects issues with the torque converter clutch solenoid’s operation. The torque converter clutch creates a secure connection between the engine and transmission, which improves fuel economy and lowers transmission fluid temperatures. The transmission control module (TCM) uses information from multiple sensors to determine whether to engage or disengage the torque converter clutch. A solenoid valve controls the flow of automatic transmission fluid to engage the clutch.

Note: The definition of code P2757 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database to learn how to fix a P2757 code.

What are the Common Causes of the P2757 Code?

There are numerous potential causes of the P2757 code. Here are some of the most common causes of P2757 code.

• Failed torque converter
• Defective torque converter solenoid
• Wiring problem
• Low or dirty transmission fluid
• Valve body problem
• Internal transmission failure
• An issue with the TCM, such as software in need of an update

What are the Common Symptoms of the P2757 Code?

There might be more than one DTC stored in your vehicle’s powertrain control module (PCM). If the P2757 code is accompanied by other DTCs, you might notice some symptoms not present on this list. However, if the PCM is only storing a P2757, your vehicle might exhibit the following.

• Illuminated check engine light
• Reduced fuel economy
• Torque converter engagement problems
• Possible transmission shift issues

How to Diagnose the P2757 Code

There are many trouble codes for a vehicle’s transmission system apart from P2757. Some codes you might encounter are P2714, P2713, P2715, P2716, and P2717.
