How to Fix Code P0744: A Step-by-Step Guide

Code P0744 is a diagnostic trouble code (DTC) that indicates a problem with the torque converter circuit in your car’s transmission. It is also known as a “shift solenoid malfunction” code, and can cause your transmission to shift erratically or fail to shift at all.

To fix this issue, you will need to diagnose and repair the underlying cause of the code. This may involve replacing the shift solenoid, flushing the transmission fluid, or adjusting the linkage on the transmission. You may also need to replace any damaged or worn out components such as sensors or internal parts.

In order to diagnose this issue correctly, it is important to use a professional scan tool and follow the manufacturer’s instructions for diagnosis and repair. This will help you narrow down possible causes and determine which parts need to be replaced or adjusted. Once you have identified the problem, you can then move forward with repairing the issue and restoring your vehicle’s performance.
