Common Global Transmission Error Codes

If your vehicle is experiencing an error code that begins with “P”, then it indicates that you have a problem with the Powertrain, which could mean a transmission problem. This article with discuss how to know what your error code means.

Two Types of Error Codes

Error codes can be summed up in types of codes: Global error code and manufacturing error code. Global error codes are common to all vehicles and will have the number “0” as the second character in the error code. Manufacturing error codes are specific to the manufacturer and will have the number “1” as the second character in the code. We will be just be discussing global error codes today.

Common Global Error Codes for Transmission Problems

P0218 – Transmission Over Temperature / Transmission Fluid Over Temperature

An overheating transmission is usually the issue. The cause could be low transmission fluid, issue with cooling fan, faulty fluid sensor, restricted lines, transmission issue, etc.

P0613-P0614 – Transmission Control Module System Fault (TCM) / Engine Control Module (ECM)/TCM Incompatible

Programming error, faulty electrical connection with the TCM, etc. Incompatibility with TCM and ECM.

P0700 – Transmission Control System Malfunction

TCM and ECM unable to communicate or not properly configured with parts.

P0706 — Transmission Range Sensor/Switch Range/Performance Problem

Dirty transmission fluid, defective/corroded manual shift valve, or faulty transmission range sensor

P0715 – Input/Turbine Speed Sensor A Circuit

Usually caused by a problem with shift solenoid, engine coolant sensor, valve body, or input/output speed sensor.

P0720 – Output Speed Sensor Circuit Malfunction

Inadequate signal from the output speed sensor, irregular difference between RPM input/output sensor. Possibly defective output sensor, engine coolant temperature sensor, or dirty transmission fluid.

P0729-P0736 – Gear Ratio Issue

Possibly caused by low transmission fluid, damaged solenoid, or malfunctioning torque converter.

P0750-P0770 – Solenoid Issue

This code can cause problems with shifting. Possibly a solenoid failure or solenoid issue.
