For owners of Dodge and Ram trucks equipped with the robust 47RE transmission, having the ability to monitor its health is crucial. One of the most valuable tools for this is an OBD2 scanner. Understanding which OBD2 scanner is best suited for reading your 47RE transmission temperature and performing other diagnostics can save you time and money in the long run. Let’s explore what to look for in an OBD2 scanner when dealing with a 47RE transmission.
When it comes to diagnosing your 47RE transmission, simply having any OBD2 scanner might not be enough. While all OBD2 scanners should be able to read basic engine codes, accessing specific data like transmission temperature, especially on older vehicles, requires a more capable device. You need to ensure the scanner you choose can accurately communicate with your truck’s computer and pull the necessary data.
Several brands are well-regarded in the DIY automotive community for their scanner capabilities. Foxwell, Innova, and Bosch/OTC are often recommended for their range of features and vehicle compatibility. Foxwell scanners, particularly models like the NT624 Pro or NT520 Pro (with appropriate manufacturer coverage), offer a good balance of features and price. Innova and Bosch/OTC (especially OTC models designed for DIYers) are also strong contenders, with OTC having a long history in professional-grade tools.
A key feature to look for beyond basic code reading is “bi-directional control,” often listed as “functional tests” or “ABS bleed” capability. This indicates the scanner can do more than just read codes; it can command the vehicle’s systems to perform tests, which can be invaluable for thorough diagnostics. For 47RE transmission owners, ensuring the scanner can read live data, including transmission temperature, is paramount.
Before purchasing any OBD2 scanner for your 47RE transmission, especially to monitor transmission temperature, verify its compatibility with your specific vehicle year and model. Contacting the manufacturer’s support or checking product descriptions for compatibility details is highly recommended. Furthermore, purchase your scanner from a retailer with a straightforward return policy. This precaution is wise, as even advanced scanners can sometimes have compatibility quirks or inaccuracies with certain vehicle systems or data points, like potentially misreading transmission temperature. Having the option to easily return the device if it doesn’t accurately read your 47RE transmission data provides peace of mind and protects your investment.
In conclusion, selecting the right OBD2 scanner for your 47RE transmission involves considering brand reputation, feature sets, and, crucially, compatibility and accuracy in reading transmission temperature. Brands like Foxwell, Innova, and Bosch/OTC offer viable options. Always prioritize scanners with bi-directional control and live data capabilities, and ensure you can easily return the tool if it doesn’t meet your diagnostic needs for your 47RE transmission.
