A Scan Tool For Troubleshooting Transmission Codes is an essential tool for any mechanic or car enthusiast. Transmission problems can be difficult to diagnose and repair, but a scan tool can help you quickly identify the problem and get your car back on the road.
Transmission Scan Tool Diagnosis
What is a Transmission Code?
Your car’s computer system uses transmission codes to communicate information about the transmission’s health and performance. When a problem is detected, the computer stores a code in its memory, which can be read by a scan tool.
These codes are part of the onboard diagnostics system (OBD-II), which became mandatory for all vehicles sold in the United States in 1996. The OBD-II system helps to monitor the performance of your vehicle’s engine and emissions systems, and it can also provide valuable information about your transmission.
Why Do I Need a Scan Tool for Transmission Codes?
A scan tool allows you to read and interpret transmission codes, which can be incredibly helpful in identifying the root cause of transmission problems. Without a scan tool, diagnosing transmission issues can be a time-consuming and expensive process of trial and error.
Here are some key benefits of using a scan tool for troubleshooting transmission codes:
- Accurate Diagnosis: Scan tools provide specific codes related to the transmission, pinpointing the problem area accurately.
- Time-Saving: Instead of manually inspecting various components, a scan tool helps you zero in on the issue quickly.
- Cost-Effective: Early detection of transmission issues through code reading can prevent costly repairs down the line.
- DIY Repairs: For the mechanically inclined, a scan tool empowers you to diagnose and potentially fix some transmission problems yourself.
Mechanic Reading Transmission Codes
Types of Transmission Scan Tools
There are various types of scan tools available, each with different features and price points.
- Basic Code Readers: These affordable tools can read and clear basic transmission codes.
- Advanced Scan Tools: Offering more in-depth data, these tools can read live data streams, perform bi-directional controls, and access manufacturer-specific codes.
- Professional PC-Based Scan Tools: Professional pc based scan tools connect to a computer, providing the most comprehensive diagnostic capabilities. They often include software with advanced features like graphing, data logging, and technical diagrams.
The best scan tool for you will depend on your needs and budget. If you’re a car enthusiast who likes to do your own repairs, a basic code reader or an advanced scan tool may be sufficient. However, if you’re a professional mechanic, you’ll need a professional-grade scan tool to diagnose and repair complex transmission problems.
How to Use a Scan Tool for Troubleshooting Transmission Codes
Using a scan tool is generally straightforward, but the exact process can vary depending on the tool and vehicle model.
Here are the general steps involved:
- Locate the OBD-II Port: This port is typically located under the driver’s side dashboard.
- Connect the Scan Tool: Plug the scan tool into the OBD-II port.
- Turn on the Ignition: Turn the ignition key to the “on” position but don’t start the engine.
- Read the Codes: Follow the scan tool’s instructions to read the stored transmission codes.
- Interpret the Codes: Look up the code definitions in the scan tool’s manual or online.
- Diagnose and Repair: Based on the code(s) and any accompanying symptoms, diagnose the problem and make the necessary repairs.
OBD-II Port Location
Note: Some codes may be historical (meaning they are no longer active), so it’s essential to consider the vehicle’s symptoms and history along with the codes.
Common Transmission Codes and Their Meanings
Here are some common transmission codes you might encounter:
- P0700: Transmission Control System Malfunction
- P0705: Transmission Range Sensor Circuit Malfunction (PRNDL Input)
- P0715: Input/Turbine Speed Sensor Circuit Malfunction
- P0720: Output Speed Sensor Circuit Malfunction
- P0730: Incorrect Gear Ratio
Pro Tip from John Miller, Senior Automotive Technician: “Always research the specific code for your vehicle make and model as interpretations can slightly differ. Resources like online forums and repair manuals can provide valuable insights.”
Tips for Choosing the Right Scan Tool
- Compatibility: Ensure the scan tool is compatible with your vehicle’s make, model, and year.
- Features: Consider the features you need, such as live data streaming, bi-directional controls, and ABS/SRS system access.
- User Friendliness: Opt for a scan tool with a clear display, intuitive interface, and easy-to-understand instructions.
- Updates: Choose a scan tool that offers software updates to keep up with the latest vehicle technologies.
- Budget: Set a budget beforehand and explore options within your price range.

Frequently Asked Questions
1. Can a scan tool clear transmission codes?
Yes, most scan tools have the capability to clear stored transmission codes. However, it’s important to address the underlying problem that triggered the code in the first place. Simply clearing the code without resolving the issue will likely result in the code reappearing.
2. Do I need a professional mechanic to use a scan tool?
While professional mechanics utilize advanced scan tools, there are user-friendly options available for car owners. Basic and mid-range scan tools are designed for DIY enthusiasts and can provide valuable information for troubleshooting.
3. Are there handheld scan tools specifically for transmissions?
Yes, some manufacturers offer club car handheld scanner designed specifically for diagnosing transmission problems. These specialized tools may provide more in-depth information and functionalities related to transmission systems.
4. Can a scan tool tell me the remaining lifespan of my transmission?
While a scan tool can’t predict the exact lifespan, it can reveal issues that, if left unaddressed, can significantly impact transmission longevity. Regularly scanning for codes and monitoring transmission performance can provide insights into its overall health.
5. What are some reliable brands for transmission scan tools?
Several reputable brands specialize in automotive diagnostic equipment, each with its own strengths. When choosing a scan tool, consider factors like features, ease of use, compatibility, and customer reviews to make an informed decision.
