P0730 – Incorrect Gear Ratio – Transmission Fault Code | CodeMechanic

Описание: This video explains one of the most common automatic transmission fault codes found in modern vehicles. Each episode in this series breaks down what the code means, the symptoms it causes, and why it affects the shifting performance of your car or truck.
We cover key transmission components such as shift solenoids, pressure control solenoids, input and output speed sensors, torque converters, valve bodies, fluid temperature sensors, and internal clutch systems.
You’ll learn where the related sensor or component is located, how to test it properly, and the correct steps to diagnose and repair the issue using professional methods.
Whether your vehicle is experiencing delayed shifts, harsh shifting, slipping, limp mode, overheating, or gear ratio problems, this guide gives you clear and accurate information to help you understand and fix the problem correctly.
This series is ideal for anyone working on automatic transmissions, including DIY mechanics, technicians, or drivers who want to understand what causes transmission errors and how to address them.
