A P0734 trouble code indicates that an abnormality has been detected in the gear ration of one of the automatic transmissions gears, causing the storage of a code in the Powertrain Control Module (PCM) and illumination of the Check Engine Light.
How do I fix error code P0734?
What Repairs Will Fix P0734?
- Change transmission fluid / filter.
- Repair or replace damaged wiring and/or connectors.
- Repair or replace failed transmission or torque convertor component.
What does P0734 mean?
Code P0734 When the code P0734 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing a greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor when the vehicle is in 4th gear.
How do I fix code P0733?
Repairs that can fix a P0733 code would include:
- Replacing a shift solenoid.
- Replacing the powertrain control module.
- Replacing the transmission module (if applicable)
- Adding or replacing the transmission fluid and filter.
- Overhauling the current transmission.
- Installing a brand new transmission.
What causes P0731 code?
The P0731 code occurs when the PCM detects a discrepancy between the speeds of first gear’s input RPM sensor and transmission output RPM sensor. As a result, the vehicle cannot shift into first gear, and it could indicate that the transmission is slipping.
What does transmission fluid pressure low mean?
If the fluid is low, it should be assumed that there is a leak in the system, and the mechanic should begin searching for where the leak is coming from. Depending on the location of the leak, it may be able to be repaired, and the issue resolved.
How do I fix error code P0740?
Repairs that can fix the P0740 code may include:
- Replacing the torque converter clutch solenoid.
- Replacing the torque converter or clutch.
- Adding or replacing transmission fluid and filter.
- Replacing the powertrain control module.
- Overhauling the current transmission.
- Replacing the transmission with a brand new one.
What can cause a P0733 code?
Here are some common triggers of the error code P0733:
- Low transmission fluid level.
- Dirty transmission fluid.
- Bad shift solenoids.
- Internal transmission problems.
- A faulty valve body.
- Circuit problems, such as damaged wiring and poor connections.
- An issue with the PCM or TCM, such as software in need of an update.
Where are the shift solenoids located?
valve body assembly
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.
