Yur transmission might be bad, or you need to replace your TCM. Dodge Neon P0734 OBD-II Diagnostic Powertrain (P) Trouble Code: This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows: Reason For Dodge Neon P0734 Code: The reason of Dodge Neon P0734 OBD-II Engine Trouble Code is P0734 Gear 4 Incorrect ratio. 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. This can occur during shifting or when driving at steady speeds. It often implies that the transmission is slipping. P0734 Diagnostic Theory for Shops and Technicians When diagnosing a P0734 code, it is important to record the freeze frame information and then to duplicate the code setting conditions with a test drive. Pay close attention to the engine load, throttle position, RPM, and road speed because a P0734 can be difficult to detect. One should monitor the RPM input speed and compare that to output speed RPM on a smooth, flat surface after the vehicle is warmed up and the fuel system is in a closed loop. Monitor how the 4th gear solenoid configuration responds to an increased amount of throttle. The 4th gear related solenoids should stay in the 4th gear configuration and the transmission should NOT slip.
