What is the P0730 Code?

The P0730 code is a generic OBD-II trouble code that indicates a problem with the transmission. Specifically, it refers to an "Incorrect Gear Ratio." This means that the transmission control module (TCM) has detected that the actual gear ratio does not match the expected gear ratio for the current driving conditions.

Common Causes of P0730 Code

Understanding the potential causes of the P0730 code can help you diagnose the issue more effectively. Here are some common reasons why this code may appear:

1. Transmission Fluid Issues

   • Low transmission fluid levels
   • Contaminated or old transmission fluid

2. Faulty Transmission Control Module (TCM)
