What does engine code P0742 mean?

Spread the love

When the P0742 code appears, it means that the amount of torque converter lock up required is not in line with the amount that is actually detected. The transmission control module will detect the slippage on the torque converter clutch when the converter is commanded off.

What does shift solenoid B stuck on mean?

Common reasons are: Hydraulic blockages happening inside the internal transmission fluid passages. Malfunctioning shift solenoid. Low transmission fluid. Transmission fluid that is dirty or otherwise contaminated.

What happens when a torque converter clutch solenoid goes bad?

Damaged Torque Converter Clutch Solenoid If the solenoid is faulty, there won’t be an accurate measure of how much transmission fluid is a need which could lead to abnormal fluid pressures. As a consequence, there could be irregular behaviors such as poor gas mileage, engine stalling, among others.

How much does it cost to replace a torque converter clutch solenoid?

On average individual solenoids cost between $15-$30, with prices reaching as high as $100, according to Autoservicecosts. Depending on the number of solenoids you need to replace and service time, labor costs will range from $70–$150.

Can you replace a torque converter clutch solenoid?

Replacing A Torque Converter Clutch Solenoid Whenever any of these fail, you will not be able to generate the necessary pressure in the torque converter to shift gears effectively. It is very common to replace all these parts when replacing a TCC solenoid. All of these parts can go out at the same time.

Is it safe to drive with a P0740 code?

A P0740 code should always be addressed immediately to prevent further damage to the vehicle. It may be unsafe to drive if this trouble code is accompanied by drivability symptoms.

How do you bypass a shift solenoid?

To bypass the shift and TCC solenoids, you simply need to connect standard 194 light bulbs to these individual circuits coming from the PCM and then connect the other side of the bulbs to ignition B+. The light bulbs will then serve as a “load” which will simulate the solenoids.

How do you fix a torque converter clutch solenoid circuit performance or stuck off?

  1. Replace the torque converter clutch solenoid.
  2. Replace the torque converter or clutch.
  3. Change transmission fluid and filter.
  4. Repair/replace damaged wiring and connectors.
  5. Repair/replace TCM or ECU.
  6. Install a rebuilt or remanufactured transmission.

Will a torque converter throw a code?

Will a bad torque converter throw a code? Sometimes, but not always. Most torque converter-related codes have to do with the torque converter clutch. Other issues with the converter are less likely to set a code.

Will a bad shift solenoid throw a code?

Q: Will a bad shift solenoid always throw a code? When you diagnose your vehicle for solenoid problems using a scanner, you’ll always see trouble code. This trouble code may persist even after troubleshooting the engine, and this means the fault is yet to be fixed.

What are the symptoms of a failing torque converter?

  • Loss of Acceleration.
  • Slipping Between Gears.
  • Vehicle Won’t Shift at All.
  • Transmission is Overheating.
  • Transmission Fluid Leak.
  • Bad Transmission Fluid.

What does engine code P0752 mean?

Diagnostic trouble code (DTC) P0752 stands for “Shift Solenoid “A” Stuck On.” This code sets when the transmission control module (TCM) detects that a shift solenoid is not functioning as expected. Automatic transmissions typically have three solenoids referred to as A, B, and C.

What causes code P1870?

More About the P1870 Code This code is generally an indication that your transmission is slipping, which can cause undue wear and damage to the vehicle’s clutch packs.

What is code P0756?

Code P0756 means that the vehicle’s PCM sensed an irregularity in shift solenoid B, which is located in the transmission. As a computer-controlled transmission, shift solenoids are used to manage how fluid is transferred from hydraulic circuit to hydraulic circuit.

How do you fix a stuck solenoid B?

  1. Changing the transmission fluid and filter.
  2. Replace faulty solenoid.
  3. Repair or replace a faulty transmission pump.
  4. Repair or replace defective transmission valve body.
  5. Perform transmission flush to clean passages.
  6. Cleaning corrosion from connectors.
  7. Repairing or replacing wiring.

How much does it cost to fix a solenoid?

This job typically takes 2-4 hours to complete, and shop time is generally billed at $60 – $100 per hour. The average total cost to diagnose and replace one ranges between $150 and $400. Depending on the make and model of your vehicle, expect to pay between $15 – $100 for a single transmission shift solenoid.

Where is the transmission shift sensor located?

The shift solenoid is located in the valve body assembly which is within the transmission. Typically, these solenoids can be replaced without removing the transmission but the job requires care and attention to detail.

Can I drive with a bad torque converter clutch solenoid?

IF it’s stuck in the off position (the most common mode of failure) , then yes, the car can be driven. The fuel economy will be lower. And the check engine light will probably be on., and you may notice a slightly different tone from the engine. But it can be driven.

What are the symptoms of a bad TCC solenoid?

The main symptom of a TCC solenoid failure is the converter is not locking up. When the converter is not locking up you will notice the engine’s RPMs staying higher under load at highway speeds. Another symptom of a failed TCC solenoid is a fault code.

What happens if you drive with a bad torque converter?

A bad torque converter can damage a transmission. Bad torque convertors can lead to damage, overheating, friction, and transmission fluid degradation. If these problems continue, it can cause even more damage to transmission.

Can you replace a torque converter without removing the transmission?

The good news is, if it is just your torque converter that is having issues since it’s a self-contained unit, you may not need to replace or rebuild your whole transmission. Torque converters can be serviced or replaced as a single unit.
