P0734 Code: Gear 4 Incorrect Ratio
P0734 Code: Gear 4 Incorrect RatioDiagnostic trouble code (DTC) P0734 stands for “Gear 4 Incorrect Ratio.” It is triggered once your PCM detects that the RPM difference between the rotational speed of your input speed sensor and the transmission output speed sensor doesn’t match what the ECM/PCM expects to see in 4th gear.
