Easiest Fixing of P2757 Toyota Tundra!

What Does P2757 Toyota Tundra Code Mean? P2757 is an error code for Toyota Tundra, which represents the Solenoid of the Torque Converter Clutch is stuck off or is giving a very poor performance.

The Torque Converter Clutch (TCC) Solenoid is an essential equipment for a car that is needed to regulate fluid pressure by measuring the appropriate fluid required for the lockup clutch.

If the TCC does not work properly or gets damaged for some reason, the fluid pressure will be imbalanced, and your engine will not function appropriately. This type of condition is known as the P2757 error code.

P2757 Toyota Tundra- Causes, Symptoms & Fixes

Find out the causes and symptoms to get the overall idea of this error code.

Faulty pressure control solenoid circuitFacing problems during gear shifting or delayed during shifting
Faulty Electronic Control Unit (ECU)Turning off the engine for no reason or failing to command flex lockup
Low fluid pressureGetting unpleasant noise or burning smell
Blockage in hydraulicIncreasing temperature of the engine and low fluid pressure

From the table, you got an overview of P2757 symptoms and causes. In the below, we will elaborate on the cause and will give the easiest solutions to these problems. Moreover, to get prevention tips you must read the article to the end.

Faulty Pressure Control Solenoid Circuit

The function of the pressure control solenoid circuit is vital as it controls the fluid pressure. When the solenoid becomes damaged, the gear shifting becomes so tough.

Besides, it is also a reason for the transmission overheating. Overall, if your pressure control solenoid circuit is faulty, the performance of the TCC pressure control solenoid becomes poor.

Solution: There are different types of solutions for different conditioned faulty pressure control solenoid circuits.

  • If the pressure control valve is damaged then replace the valve.
  • If you observe impurities on the tube or surface, clean the tube as well as the surface.
  • If you detect corrosion of the solenoid, you should replace the defective elements.

Faulty Electronic Control Unit (ECU)

The electronic control unit is a system in a car that controls the electrical system in a vehicle. For example, commanding flex lockup in the car during high-speed riding.

After huge investigations, experts say that if the voltage remains around 7.0 volts, you can avoid the P2757 error code.

If the ECU system of your car malfunctions, then it can not command the flex lockup. So voltage may fluctuate, and the performance of the TCC solenoid starts to fall.

Solution: Though you can repair the ECU, the cost is very high, about $1000 to $3000. So the best solution for solving a faulty electronic control unit is to replace it.

We will recommend you take your car to a certified technician to replace the ECU. But do not worry. The procedure is very simple and quick. 15 minutes are enough to do the task.

[NOTE: Remember to charge the battery over 12 volts before the procedure starts.]

Low Pressure Of Fluid

Shortage of fluid is a partial reason for the P2757 code. When your car engine has a shortage of fluid, the transmission problem occurs. Low pressure of fluid causes poor Torque Converter Clutch solenoid function.

Solution: Keep in mind to check the fluid of your car. Fill up the fluid tank with fresh and sufficient fluid before ending up the whole fuel.

[NOTE: Avoid exceeding the fluid line while filling the fuel.]

Blockage In Hydraulic

Blockage in hydraulic is an irritating issue that also can hamper the TCC solenoid purpose.

When you use adulterated fuel for your car, the blockage occurs occasionally. Furthermore, if you do not take care of your car and do not clean or wash it periodically, the blockage is obvious.

Solution: You should use fresh and pure fuel to avoid any engine or solenoid-related difficulties. In this case, we will suggest you use amber or red color fuel and avoid other color fuel.

Cleaning up dirt regularly is an awesome way to reduce blockage in hydraulics.

So! We hope now you have no other confusion about the P2757 code for Toyota Tundra after knowing the P2757 fix.

Prevention Tips

We believe that prevention is always a better option. So we present a prevention tip list for you.

  1. Always avoid faulty TCC(Torque converter clutch) solenoid; otherwise, it will damage the engine.
  2. Choose the ECU correctly to avoid P2757 fault code popups. You should go with flex-fuel and knock control. Similarly, long-term data logging is important.
  3. Keep filling up the fuel tank to avoid a shortage of fluid.
  4. Clean up dirt regularly.

Frequently Asked Questions (FAQs)

How do I know if my TCC solenoid is bad?

You can identify some irritating symptoms if your TCC solenoid is bad. Such as;
Troubling during gear shifting.
Incapacity to downshift the gear.
Taking a huge amount of time for gear shifting.

Where is the torque converter solenoid located?

Torque converter is located in the middle of the car engine’s flexplate and transmission. It balances the fluid pressure of the engine.

Can I repair my own ECU?

Yes, you can repair the ECU, but it’s better to take it to a certified technician. We also want to let you know that the repair cost of ECU is very high. So, it is better to replace the ECU.


The P2757 Toyota Tundra error code is a serious issue and may seem quite challenging to fix. We tried to present the easiest solution to you. So, now we hope you have no confusing questions about the error code.

And the prevention tips will benefit you to resist the P2757 error code to protect your Tundra for a long time. Stay tuned for more easy solutions to your difficult problems.
