P0734 Gear 4 Incorrect Ratio

General Information

Component Location





General Description

Input speed sensor value must be equal Output speed sensor value times each gear ratio at each gear position of transmission. That operation value equal with TCM operation value. For example Output speed sensor value is 1000 RPM and 4th speed gear ratio is 1.4 then Input speed sensor value must be 1400 RPM.

DTC Description

This code is set when Input speed sensor value is different with TCM operation value, caused by control valve sticking, solenoid valve fault (most of fault is mechanical, rarely electrical fault).
