How to identify a Dodge Ram transmission?


As a seasoned auto repair expert at Kevin's Autos, I’ve encountered countless Dodge Ram trucks in my years of service. One of the most common questions I get from customers is how to identify the transmission in their Dodge Ram. Whether you're troubleshooting an issue, planning a repair, or simply curious, knowing how to identify your transmission is crucial. In this guide, I’ll walk you through the steps to accurately identify the transmission in your Dodge Ram.


Why Identifying Your Transmission Matters


Your Dodge Ram’s transmission is a critical component that ensures your truck runs smoothly. Identifying the correct transmission model is essential for:



  • Ordering the right replacement parts.

  • Ensuring compatibility with fluids and maintenance procedures.

  • Diagnosing issues accurately.

  • Understanding your vehicle’s capabilities, such as towing capacity.


Steps to Identify Your Dodge Ram Transmission


Follow these steps to determine the transmission type in your Dodge Ram:



  • Check the Owner’s Manual: The easiest way to identify your transmission is by consulting your Dodge Ram’s owner’s manual. It will list the transmission type and specifications for your specific model and year.

  • Look for the Transmission Identification Tag: Most Dodge Ram transmissions have an identification tag or stamp located on the transmission housing. This tag includes a series of numbers and letters that indicate the transmission model.

  • Decode the VIN (Vehicle Identification Number): Your truck’s VIN can provide valuable information about its transmission. You can find the VIN on the driver’s side dashboard or door frame. Use an online VIN decoder or consult your dealership to determine the transmission type.

  • Inspect the Transmission Pan: The shape and size of the transmission pan can also help identify the transmission. For example, Dodge Ram trucks often use the 46RE, 47RE, or 68RFE transmissions, each with distinct pan shapes.

  • Consult a Professional: If you’re still unsure, bring your Dodge Ram to a trusted auto repair shop like Kevin’s Autos. We have the tools and expertise to identify your transmission quickly and accurately.
