P0896 Switching time too long

P0896 – OBD-II Trouble Code Technical Description

Trouble code P0896 indicates that the gear shift time is too long.

What does the fault code mean P0896?

Trouble code P0896 indicates that the automatic transmission's shift times are too long. This may indicate problems with the transmission that may affect its performance and operation. If this code is stored in your vehicle, it means that the powertrain control module (PCM) has received an input signal from the input and output speed sensors that indicates that the shift interval between gears is too long. If the PCM detects that the shift time is too long, a P0896 code may be stored and the Malfunction Indicator Lamp (MIL) will come on.

Fault code P0896.

Possible reasons

Some of the possible causes of the P0896 trouble code are:

  • Problems with speed sensors: Malfunction or incorrect reading of signals from speed sensors at the input and output of the transmission.
  • Transmission control valve problems: Defective transmission control valves can cause delays in shifting gears.
  • Transmission Solenoid Problems: Faulty solenoids can result in improper shift control.
  • Problems with the gear shift mechanism: Worn or damaged gear shift mechanism may cause delays in shifting.
  • Low or contaminated transmission fluid: Insufficient fluid levels or contamination can make it difficult for the transmission to function properly.
  • Problems with electrical connections: Broken, corroded or incorrectly connected wires can cause erroneous transmission readings.
  • PCM software problems: Faults in the PCM software can cause transmission data to be misinterpreted.

These are just common causes and additional tests need to be carried out for an accurate diagnosis.

What are the symptoms of a fault code? P0896?

Symptoms for a P0896 trouble code can vary depending on the specific problem and vehicle characteristics, but some of the possible symptoms that may accompany this code include:

  • Slow or delayed gear shifting: The automatic transmission may shift to the next gear too slowly or with a delay.
  • Hard or jerky gear shifting: Gear changes may be rough or feel rough.
  • Unusual noises or vibrations: If gears are not shifted correctly, unusual noises or vibrations may occur in the transmission or suspension areas.
  • Acceleration issues: The car may have trouble accelerating due to improper gear shifting.
  • Malfunction indicator lamp (MIL): The malfunction indicator lamp on the instrument panel lights up.
  • Degraded performance and fuel economy: If the transmission is not operating properly, vehicle performance and fuel economy can be affected.

If you notice any of these symptoms, it is recommended that you have your vehicle diagnosed and repaired by a qualified auto mechanic.

How to diagnose a fault code P0896?

The following steps are recommended to diagnose DTC P0896:

  1. Scan error code: Use an OBD-II scanner to read the error code and check its exact meaning.
  2. Checking other error codes: Check to see if there are other error codes in the ECM (engine control module) or TCM (transmission control module) that may be related to shifting problems.
  3. Checking the level and condition of the transmission fluid: Check the level and condition of the transmission fluid. Low or contaminated fluid levels can cause shifting problems.
  4. Checking speed sensors: Check the operation of the speed sensors at the input and output of the transmission. Make sure they work correctly and are not damaged.
  5. Checking transmission valves and solenoids: Check the condition and functionality of the transmission control valves and solenoids. Faults in these components can cause shifting problems.
  6. Checking electrical connections: Check electrical connections, including transmission-related wires and connectors. Make sure they are not corroded, broken or overlapped.
  7. Software diagnostics: Check the ECM and TCM software for updates or faults that may cause shifting problems.

After diagnosis, it is recommended to carry out the necessary repair actions or contact professionals for additional diagnostics and repairs.

Diagnostic errors


When diagnosing DTC P0896, the following errors may occur:

  1. A complete diagnosis has not been carried out: Some mechanics may attempt to replace transmission components without performing a full diagnosis, which may result in the problem being addressed incorrectly.
  2. Ignoring other error codes: Some other error codes, such as those related to speed sensors or electrical connections, may also be causing the problem, but they can be overlooked.
  3. Incorrect interpretation of data: Interpretation of scanner data may be incorrect, which may lead to incorrect diagnosis and resolution of the problem.
  4. Incorrect cause identification: The fault can be caused not only by the shifters themselves, but also by other factors such as electrical problems, problems with speed sensors or even transmission control software.
  5. Incorrect component replacement: Replacing components without identifying and addressing the root cause can lead to additional problems and repair costs.

To avoid these errors, it is recommended to carry out a full diagnosis using suitable equipment.

How serious is the fault code? P0896?

Trouble code P0896 indicates a problem with gear shift timing, which can have a negative impact on transmission performance and overall vehicle performance. Although a vehicle with this error code will still be drivable in most cases, incorrect or delayed shifting can cause additional wear on the transmission and result in poor fuel economy and performance. In the long term, transmission problems can lead to serious problems and increase the risk of accidental breakdown. Therefore, it is recommended that you take action to eliminate the causes of this error code as soon as possible to avoid further transmission problems and ensure the safe and efficient operation of your vehicle.

What repair will help eliminate the code? P0896?

Troubleshooting trouble code P0896 may involve several steps depending on the specific cause of the problem. Below are some common repair methods:

  1. Checking and replacing transmission fluid: The first step may be to check the level and condition of the transmission fluid. If the level is low or the fluid is contaminated, it is recommended to replace it.
  2. Checking and replacing speed sensors: Check the operation of the speed sensors at the input and output of the transmission. Replace sensors if necessary.
  3. Checking and replacing transmission solenoids: Check the operation of the transmission solenoids and their electrical connections. Replace solenoids if necessary.
  4. Checking and replacing transmission control valves: Check the condition of the transmission control valves. If they are damaged or stuck, replace them.
  5. Software diagnostics: Check your transmission control software for updates or errors. If necessary, update or flash the ROM.
  6. Checking electrical connections: Check electrical connections, including transmission-related wires and connectors. Make sure they are free of corrosion and breaks.
  7. Checking external factors: Check for external factors such as damaged wires or sensors that may interfere with the transmission's normal operation.

After completing these steps, it is recommended that you conduct a test drive and re-diagnosis to check if the problem has been successfully resolved. If the problem persists, further evaluation or assistance from a qualified technician may be required.
