The definition of code P2764 is “Torque Converter Clutch Pressure Control Solenoid Control Circuit Low.” This code indicates that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has identified a problem with your vehicle’s torque converter clutch pressure control solenoid control circuit. This circuit turns on the solenoid, which controls the torque converter clutch pressure, which creates a connection between the engine and transmission. You may see this code in any OBD-II vehicle, as it’s a generic powertrain code.
More About Error Code P2764
The Torque Converter Clutch, also called the Torque Converter Lockup Clutch, is an important part of your transmission. It allows your transmission to stay engaged even when the wheels are stopped. Creating an active mechanical connection between the engine and transmission eliminates energy-wasting slippage problems in the torque converter. The vehicle uses hydraulic fluid to apply this clutch, but the Transmission Control Module (TCM) needs to know when to apply it. This code indicates that either the clutch solenoid or the control circuit has responded with an issue.

What Are the Symptoms of a P2764 Code?
There are many symptoms you might experience with the P2764 code, primarily having to do with your transmission. For example, you might experience harsh, erratic shifting and shift slipping. When in gear, your engine may stall or even refuse to move. This can also lead to your transmission overheating. In some vehicles, your PCM may engage “Limp Mode,” also called “Limp Home Mode,” a failsafe mode limiting the engine’s response to keep your vehicle safer while you get home. It’s also common to see increased fuel consumption and a generally lower fuel economy. Finally, you can expect to see the check engine light turn on.
What Are Some Causes of a P2764 Code?
You might see the P2764 error code for all sorts of reasons, and you mustn’t overlook any of them while you diagnose the issue. Here are just a few of the causes you may need to check for the P2764 code:
- Dirty or insufficient transmission fluid
- Dirty transmission fluid filter
- Transmission fluid leak
- Frayed wiring or damaged connectors
- Faulty torque converter clutch pressure control solenoid
- Faulty torque converter clutch
- Faulty torque converter
- Other internal pressure problems
- Valve body issue
- PCM, ECM, or TCM failure
Some of these causes will be more likely than others, but it’s still important to understand all sorts of potential causes to which the P2764 code might be related.
How Serious Is the P2764 Code?
The P2764 code is extremely serious. Any time you’re experiencing a transmission error code, it should be considered quite serious, but the P2764 diagnostic trouble code is one of the more serious options. As seen before, it can cause a huge swath of drivability concerns, including problems with fuel economy, gear slippage, and engine stalling, which can spiral into engine damage issues over time. It’s important to fix this problem as soon as possible, not just for your engine health but also because it can save you money by fixing your fuel economy problems.
Can I Still Drive with a P2764 Code?
You shouldn’t drive with the P2764 code active, even if you feel like you’re not experiencing severe drivability problems. These problems primarily concern your vehicle’s transmission, which is notably one of the most difficult and expensive parts of the engine to repair or replace if something goes wrong. Most of these causes aren’t difficult to solve, but if you keep driving and damage the transmission, it could cost you thousands of dollars and hours of labor to fix. Avoid driving when the P2764 code is active.
How Easy Is It to Diagnose a P2764 Code?
Diagnosis for the P2764 code can be extremely difficult because of how many potential causes exist. It’s not as easy as checking one or two problems for most people. You may need to check dozens of spots in your vehicle, ranging from simple visual inspections like your transmission fluid level to much more complex inspections like internal pressure problems. Many people simply choose to get help from a certified mechanic.
How Difficult Is It to Inspect a P2764 Code?
The inspection process for the P2764 code is also more complex than you might assume. To inspect the P2764 code, you need tools like a diagnostic scanner and a useful source of information, which might include wiring diagrams, technical service bulletins, and an OBD-II database. You must also understand how the P2764 code behaves in different vehicles. If you don’t feel like you know this, it’s best to hand the problem off to a professional mechanic.
Need Additional Help with Your P2764 Code?
Most people will end up getting extra help with the P2764 code, as it’s frequently a code that is too complicated for most DIYers to handle themselves. If you’re looking for a great P2764 code fix, an expert can help.
First, you should find an auto repair shop in your area. This way, you don’t have to go far, especially when dealing with a no-start condition.
The OBD-II database at KBB.com can also be extremely helpful if you’re dealing with additional codes. These codes often need their own diagnosis and inspection, sometimes before you can deal with these codes, and it’s helpful to have as much extra information as possible.
