How does a mechanic diagnose the P0734 code?ДЇixing and clearing a P0734 trouble code requires the use of an advanced OBD-II scanning tool, a manual pressure gauge, and a digital volt/ohmmeter by the mechanic. The vehicle could also suffer from the transmission slipping and overheating, a decrease in fuel efficiency, and other gear ratio codes being stored on the PCM in addition to the original code. Symptoms of a P0734 trouble code range from the failure of the transmission to shift into a particular gear to no apparent malfunction. The causes of a P0734 trouble code include a faulty PCM, ECM, or TCM blockage inside the transmission a faulty shift solenoid, dirty or contaminated transmission fluid, or a low transmission fluid condition, and a mechanical transmission failure. And when this data does not match up, a P0734 trouble code is stored. The vehicle's Engine Control Module (ECM), Transmission Control Module (TCM), or PCM, depending on the vehicle make and model, uses information from the transmission speed sensor, calculated against engine speed, to determine the proper gear ratio. The P0734 trouble code develops when there is a problem shifting into fourth gear specifically. Utilizing the position of the throttle, engine load and speed, as well as vehicle speed, the vehicle computer determines the appropriate gear to shift into to maintain the desired speed and power in an automatic transmission. 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.
