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.
What causes incorrect gear ratio code?
The incorrect gear ratio code may have several causes: Bad or dirty fluid in the transmission. Low fluid in the transmission. Broken mechanical components within transmission.
What causes P0735?
P0735 can be triggered when your vehicle is driving in 5th gear or while you’re shifting into it. With an automatic transmission, the vehicle’s computer is in charge of the shifting.
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 is a shifting solenoid?
A transmission shift solenoid is what controls the flow of transmission fluid. This is done through a module that sends an electrical signal telling the shift solenoid exactly when to transfer fluid in and out of the transmission along with the right rate.
What does a transmission control module do?
What is a Transmission Control Module? The transmission control module is an electronic component of your transmission that’s in charge of interpreting electrical signals from sensors in other parts of the vehicle.
