Guide To P2703 OBD Error Code Solutions

<<See All OBD Codes

Trouble code P2703 can be defined as Transmission Friction Element "D" Apply Time Range/Performance. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

Do you want to gain some more knowledge about the P2703 trouble code? The clutch solenoid is monitored by the Transmission Control Module. This error code would start appearing when the clutch solenoid would not be as per the specifications set by the manufacturer. This error code might give rise to harsh shifting as well as transmission slipping issues may also arise.

What causes this problem with the Transmission Friction Element "D" Apply Time Range/Performance?

• The overall ATF level might be low
• Dusty ATF
• There can be opened or shorted transmission control module harness
• Transmission mechanical troubles
• Occlusion in transmission hydraulics
• Wiring might not be functioning properly
• Inaccurate transmission valve body
• Defects in the transmission control module
• Transmission control module (TCM) circuit poor electrical connection

1. Transmission Fluid Pump Harness - The fluid pump harness can be faulty and cause transmission to underperform due to transmission slipping and harsh shift. Thus, check for harness faults and replace it now!
2. 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.
3. Automatic Transmission Module – If the transmission module is faulty, then the vehicle might experience erratic gear shifts and throttle response. The engine might also stall will accelerating and slowing down. Thus replace faulty automatic transmission module, if required.
4. 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.
5. Transmission Fluid Pump - A failed transmission fluid pump can cause the fluid not being able to circulate in the transmission and the driver may smell the fuel burning. Thus, it might need immediate replacement.
6. 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?

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 P2703 here:

Common Symptoms

• Automatic transmission fluid might
• start leaking
• Stony handling
• Transmission might start slipping
• Variable shifting
• Rare shift patterns
• Raspy shift selection
• Issues related to low torque
• Untypical power output

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P2703:

• Recondition the quirky transmission control module
• Replace the transmission control module circuit
• Rebuild the mechanical issues in the transmission
• The defective shift solenoid should be mended
• If you find out that there is a stoppage in transmission hydraulics, then it should be replaced or repaired as per the need
• You must fix the less ATF level
• Restore the grubby ATF
• Repair or replace the faulty transmission valve body
• If there is an opened or shorted transmission control module harness, then you must repair it

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

• It is essential to confirm the uprightness of the automatic transmission fluid.
• You can use the dipstick to check the level of the A/T with the vehicle running and in park.
• This procedure varies a significant amount between manufacturers.
• This information can usually be found quite easily with the service manual in the dash or sometimes even printed on the dipstick itself! Just make sure that the fluid is clean and free from debris.
• If you do not remember ever doing a transmission service, it would be a good idea to check our records and service your transmission accordingly.
• You'd probably be surprised how dirty ATF can affect the functionality of your transmission.
• You should always check ATF level on flat surface to acquire accurate readings.
• The manufacturer recommended fluid should always be used.
• Generally when you are attempting to search the connector/harness for this system, then you must search for a junction connector.
• There might be one "master" connector, so just be sure that you are working with the right one by referring to your manual.
• The connector should be seated properly to ensure perfect electrical connection.
• Where the connector is situated on the A/T, it may be subject to vibrations that could cause connections to come loose or physically damage them.
• Not to mention, the possibility of ATF to saturate connectors as well as wires causing future or present problems.
• It is always a great decision to be aware of the overall condition of your automobile.
• There is a fact that other systems can directly affect other systems.
• Rough tires, worn out suspension parts, wrong wheel, all of these might cause problems in this system and there are some other causes as well.
• So that’s the reason why it is very important to get rid of this error code.

Common Mistakes When Diagnosing The P2703 Code

• Clutch solenoid might start failing
• Some issues related to the internal transmission
• Issues with the car transmission control module
