P2760 - OBD Trouble Code

<<See All OBD Codes

Is the car transmission slipping? Are you experiencing lack of acceleration and poor gear shifts? All these are indications of transmission system problems in relation to the torque converter clutch pressure control solenoid leading to OBD code P2760 getting stored in the powertrain control module (PCM).

The torque converter clutch creates a one to one connection between the output of the engine and the input of the transmission. This increases fuel mileage and reduces transmission fluid temperatures. It’s controlled by the TCM. It sends a pulsed voltage signal to the TCC solenoid. The solenoid moves a valve that sends pressurized fluid to the clutch circuit, engaging the TCC. When the clutch is disengaged, the torque converter operates normally, allowing the engine to rotate without stalling while the vehicle is slowing and coming to a stop. While the vehicle is slowing and approaching a stop, TCC application is undesirable, because like the clutch on a manual transmission it will cause the vehicle to stall.

When the TCM senses that the torque converter clutch pressure control solenoid control circuit has an intermittent condition, OBD code P2760 gets stores in the system.

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

• Failed control solenoid valve assembly
• Open or short control solenoid valve assembly harness
• Poor electrical connection to the control solenoid valve assembly circuit
• Transmission control module faults

1. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
2. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
3. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
4. Diagnostic Tools - It is always advisable to use the correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in an efficient manner. Buy new quality diagnostic tools from us today!
5. Auto Transmission Shift Solenoid - If the TCM is unable to open the shift solenoid with the help of power or ground, it may store P2760 in the system due to faulty shift solenoid. Check and replace faulty solenoid now!
6. Automatic Transmission Valve Body Kit - A lot of issues can arise due to defective transmission valve. Thus it will affect the transmission process and the shifts can be erratic. Replace it now!
7. Automatic Transmission Filter - If there is a whining sound with delayed response from the transmission, it can be due to faulty transmission filter. Replace the damaged or clogged filter now!
8. Engine Wiring Harness - It is an important auto part which needs full care. A faulty Engine Wiring Harness can be a reason behind the flashing up of P2760 code.
9. Automatic Transmission Fluid - Always make use of correct transmission fluid and make sure that the levels always remain optimal. Thus, buy transmission fluid now
10. Torque Converter - If the vehicle’s transmission is slipping, you might have an issue with the converter. If there isn’t enough pressure to control the flow of the hydraulic transmission fluid, too much or too little will get into the transmission and cause the gears to slip as it shifts. Thus, replace faulty torque converter now!
11. Torque Converter Lockup Control - If the torque converter lockup control isn’t functioning properly, the transmission may slip along with problematic gear shifts. Thus, replace it now!
12. Torque Converter Clutch Connector - The torque converter clutch may also malfunction due to faulty connector problem. This may result in transmission slippage and faulty gear shifts. Thus, replace it now!

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2760 code to be stored:

Make use of an OBD scanner (or code reader) and a digital volt/ohmmeter to successfully diagnose this code. Just about each vehicle (with an automatic drive) made since the eighties is provided with some kind of pc controlled automatic transmission system.

OBD-II equipped vehicles utilize computerized system to calculates different engine drivability inputs using vehicle speed inputs, engine/turbine speed inputs, and transmission output speed inputs to work out the required degree of convertor clutch application necessary to realize most fuel potency, to optimize engine performance, and supply the best engine and transmission longevity.

The PCM calculates computer file and initiates convertor clutch lock up by victimization and strategically designed solenoids to actuate fluid transfer between the hydraulic circuits of the high pump and convertor. The automated transmission uses a high pump (driven by the engine via the torsion converter) to flow into fluid through the transmission hydraulic circuits within the transmission housing and valve body.

If transmission pressure is light to actuate gear changes, this sort of code is also possibly stored. Insufficient fluid pressure is most frequently caused by a dirty (contaminated) transmission fluid condition.

Begin any transmission diagnosing with a scrutiny of the transmission fluid gauge (if equipped). At any rate, make certain that the fluid level is as per manufacturer’s recommendations and in good shape. Fluid that smells burned or abnormal in any approach is ought to be thought of as inadequate.

Burned fluid may be a bound indication that the transmission has been operated throughout a contaminated fluid level condition and will have suffered harmful internal mechanical failure. If the fluid smells or seems burned, take away the transmission pan and check for the presence of clutch material and alternative detritus.

If such contaminants are found within the transmission pan, a complete, fluid flush and replacement, and a brand-new convertor are going to be needed before the transmission can perform properly. If no detritus is found within the transmission pan, visually examine all internal wiring and connectors.

Look for shorted or burned wiring and replace electronic equipment and connectors as needed. Most applications would force replacement of the complete internal transmission harness if discrepancies are noted.

If the system wiring, connectors, and parts seem to be in traditional operating order, connect the scanner to the diagnostic connexion and record all keep hassle codes and freeze frame knowledge. This info will be extraordinarily useful in diagnosis intermittent conditions which will have contributed to the present code being kept.

After the codes are cleared, operate the vehicle to visualize if the code returns. If the code fails to right away come back, you'll have an intermittent condition.

Intermittent conditions will be quite challenging to diagnose and in extreme cases might also worsen before an accurate diagnosing will be created.

If the transmission fluid seems to be in good form, however the fluid level is low, add enough fluid to find a leak and repair it. Fill the transmission with fluid, permit the vehicle to succeed in traditional operational temperature, and test drive it to visualize if the transmission operates usually and to work out whether or not the code can come back.

If the code returns and therefore the transmission slips or suffers from delayed engagement, check pump pressure employing a manual pressure gauge.

Obtain a hydraulic pressure diagram referring to the vehicle in question and thread the top of the gauge into the suitable gap on the transmission housing to record pump pressure. Compare your findings with manufacturer’s specifications and make repairs consequently.

Typical causes of low pump pressure embody clogged hydraulic passages, a defective pump, faulty shift solenoids, or a faulty electronic pressure regulator. Pump replacement would force transmission removal and partial activity. If the code in real time returns, and therefore the transmission looks to control usually, check for reference voltage and ground signals at the convertor clutch pressure management coil.

If the reference voltage and/or ground circuits are open, use the digital volt/ohmmeter to see for continuity and resistance altogether circuits. Repair or replace faulty system circuits/connectors as per requirement and retest the system to confirm that repairs were useful. Check the manufacturer’s schematic drawing for the convertor clutch pressure management coil, inspect all connected circuits and therefore the coil itself for resistance and continuity and compare your findings with manufacturer’s specifications.

Repair or replace system electronic equipment, connectors, and/or parts that fail to coincide with manufacturer’s specifications. Always retest the system to confirm a productive repair. If all system circuits are intact, connect the scanner to the diagnostic connections and arrange to manually activate the convertor clutch pressure management coil. If the coil functions properly and every circuit coincides with manufacturer’s specifications, suspect a defective converter or PCM.

Remember that PCM failure is rare and replacement would force reprogramming. If the shift coil fails to activate manually, replace the coil (or coil pack) and retest the transmission system.

Common Mistakes When Diagnosing the P2760 Code

One of the most common mistakes when you are diagnosing the P2760 trouble code is that you do not inspect the solenoid circuit when the solenoids are being replaced. The technicians should keep this thing in mind that they must look electrical components before replacing any parts which can give rise to P2760 error code.
