P0784 Dodge Description

This P0784 Dodge code indicates that the 4-5 shift valve in the valve body is locked in the direction of the spring compression. The Transmission Control Module (TCM) controls the gearshifts by turning the shift solenoid valves “ON/OFF” and switching oil pressure to the valves in the valve body. The TCM calculates the “actual” transmission gear by comparing the signals from the input speed sensor and the output speed sensor.
