Understanding Dodge Durango P0733 Code

If you're a Dodge Durango owner, you may have encountered the P0733 trouble code. This code can be alarming, but understanding what it means and how to address it can save you time and money. In this article, we will explore the P0733 code, its causes, symptoms, and potential solutions.

What is the P0733 Code?

The P0733 code is a diagnostic trouble code (DTC) that indicates an issue with the transmission. Specifically, it refers to "Gear Ratio Error in Third Gear." This means that the transmission control module (TCM) has detected a discrepancy between the expected gear ratio and the actual gear ratio when the vehicle is in third gear.

Common Causes of P0733 Code

Several factors can trigger the P0733 code in your Dodge Durango. Here are some of the most common causes:

  1. Low Transmission Fluid: Insufficient fluid levels can lead to poor transmission performance.
  2. Transmission Fluid Contamination: Dirty or contaminated fluid can affect the transmission's ability to shift gears properly.
  3. Faulty Transmission Control Module (TCM): A malfunctioning TCM can misinterpret the gear ratios.
  4. Worn Transmission Components: Components such as clutches, bands, or gears may be worn out and unable to engage properly.
  5. Faulty Speed Sensors: Speed sensors provide critical data to the TCM; if they fail, it can lead to incorrect gear ratio readings.
