Improper shifts and reduced fuel economy are the major setbacks for this kind of a problem. In extreme cases engine stalling and vehicle dying while slowing can be crucial on the road and in extreme conditions. All these are an indication of a problematic transmission thus storing OBD code P2763 in the PCM (powertrain control module) and the check engine light getting on.OBD code P2763 means Torque Converter Clutch Pressure Control Solenoid Control Circuit High Issue.

A failed transmission solenoid or an open circuit anywhere in the electrical system may cause the transmission to go into Fail Safe (or "limp" mode as it is also called) in order to protect the transmission from internal damage that might be caused by the faulty solenoid or open circuit. In fail safe/limp mode, the transmission will have limited functionality and will lock in either 2nd or 3rd gear.

When the TCM/PCM finds that the torque converter clutch pressure control solenoid circuit is having a high voltage output, OBD code P2763 gets stored.

What causes this problem with the Torque Converter Clutch Pressure Control Solenoid Control Circuit High?

• Low transmission fluid level
• Dirty transmission fluid
• Faulty Shift Solenoids
• Torque converter clutch solenoid harness is open or shorted
• Torque converter clutch solenoid circuit, electrical connection faulty
• Transmission mechanical problems
• Transmission hydraulic control circuit
• Pressure control solenoid defective

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
3. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
4. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P2763 error. Buy new diagnostic tools and equipment for us.
5. Automatic Transmission Solenoid - If the transmission solenoid is faulty, it will not be able to circulate the transmission fluid through the valve body, thus causing driving issue. Thus, replace it immediately.
6. Transmission Control Module - If the TCM has malfunctioned, it can store wrong error codes and can also cause transmission problems. Thus, replace it now!
7. Automatic Transmission Sensor - The transmission sensors help to predict the shaft speed as well as to execute correct gear ratios for the transmission system to work properly. Thus, replace faulty sensor now!
8. Auto Transmission Torque Converter - In rare cases the transmission torque converter can also be damaged, immensely harming the transmission system. Buy new parts from us!
9. Automatic Transmission Connector - Faulty connectors can be a major problem for various parts not functioning properly as well as causing damage to the wiring connection. Thus, it is important to replace faulty parts now!
10. Transmission Fluid - It is important to keep the transmission fluid at optimal levels for the hydraulic pressure system to work efficiently so that the pressure solenoids can work properly. Thus, keep the transmission fluid levels in check.
11. Torque Converter - A bad torque converter means that the flow of transmission fluid isn’t what it’s supposed to be, you can also have issues will transmission surges or lags while you drive. This will be especially noticeable at times when you’re maintaining a consistent speed.
12. Torque Converter Lockup Control - Bad lockup control will affect the transmission output thus affecting the performance and may also cause transmission slippage and overheating.
13. Torque Converter Clutch Connector - Check for damaged clutch connector and replace them immediately as they can be the prime reason for the clutch not engaging and disengaging properly.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2763 here:

Common Symptoms

• Check Engine Light illuminated (Malfunction indicator lamp)
• Delayed shift or not shifting between gear
• Transmission slipping
• Loss of fuel economy
• Transmission may overheat
• Increased fuel consumption
• In some cases, there may be performance problems, such as dying when coming to a stop after driving on the freeway and/or misfire-like symptoms

Here are some ways with the help of which you will be able to correct the OBD Code P2763.

• Refill of Low transmission fluid level
• Dirty transmission fluid to be changed
• Faulty Shift Solenoids Replacement
• Repair or replace Shift Solenoids harness which is open or shorted
• Faulty Shift Solenoids circuit, electrical connection repair/replace
• Replace transmission pressure control solenoid

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2763 code to be stored:

• A mechanic will first input an OBD-II code reader into the vehicle's computer in order to read and identify the trouble code.
• A hydraulic pressure diagram should be fed into the proper opening in the transmission system in order to take pressure readings directly from the source.
• The transmission fluid should be tested with a dipstick and checked for problems.
• Check for faulty, damaged or broken wiring and connections to the transmission pressure control solenoid and replace them immediately.
• Next, check for the continuity of the solenoid by testing the component by removing the power. If a continuity or resistance is found, expect for faulty wiring.
• Any diagnostic findings should be compared with the car manufacturer's default specifications in order to pinpoint abnormalities.
• If there are other trouble codes registered on the OBD-II reader, it may offer additional guidance in finding the root problem.

Common Mistakes When Diagnosing the P2763 Code

Oftentimes the PCM sensor and circuit is blamed, and replaced, without checking the circuit as well as neglecting the damaged wiring and connectors. Because there can be several causes for this code, a complete inspection should be carried out in order to avoid repairs that may be unnecessary and more expensive.
