Yes, you can scan a 47RE transmission with a scan tool. However, choosing the right scan tool is crucial for accurate data and helpful diagnostics. Not all scan tools are created equal, and some may not accurately read transmission temperature or other vital parameters for the 47RE. This article explores various scan tool options and factors to consider when choosing one for your 47RE transmission.
Finding the Right Scan Tool for Your 47RE
While a basic OBD2 scanner will communicate with your truck’s computer, it may not provide in-depth transmission data. For the 47RE, you’ll need a scan tool capable of reading specific transmission parameters like temperature, pressure, and solenoid operation.
Consider these brands and features:
Foxwell Scan Tools:
- Pricing: Often require separate software authorizations for different vehicle manufacturers, which can add to the cost.
- Models: NT640 (for US-manufacturer vehicles), NT624 Pro (for all manufacturers), NT520 Pro (supports two manufacturers).
- Recommendation: Contact Foxwell directly through their live chat to determine the best model for your needs and budget. Inquire about ABS bleed functions, as this can be a valuable feature for DIYers.
Innova Scan Tools:
- Wide Range: Offers a variety of scan tools for different skill levels and budgets.
- Features: Look for models with live data streaming, bi-directional control, and ABS bleed functionality.
Bosch/OTC Scan Tools:
- DIY Focus: Bosch acquired OTC and now offers several scan tools specifically designed for the DIY market.
- Affordable Options: Models like the OTC3211 provide solid functionality at a reasonable price point.
Important Considerations When Choosing a Scan Tool
- Bi-directional Control: This feature allows you to activate solenoids and perform tests, aiding in diagnostics. Look for terms like “functional tests” or “ABS bleed.”
- Vehicle Coverage: Consider your other vehicles. A scan tool that supports multiple manufacturers can be a valuable investment.
- Accurate Data: Ensure the scan tool accurately reads transmission temperature for the 47RE. Some tools may have compatibility issues with specific vehicles or data points. Buying from a retailer with a good return policy is recommended.
Beyond the Scan Tool: Using a Multimeter
If your factory service manual (FSM) provides sensor output values for different temperatures, you can use a digital multimeter to check the sensor readings directly. This can help pinpoint issues before the signal reaches the powertrain control module (PCM).
Conclusion
While many scan tools can communicate with a 47RE transmission, choosing one with the right features and compatibility is crucial for accurate diagnostics. Research different brands, compare features, and consult with the manufacturer to ensure you select the best tool for your needs. Consider features like bi-directional control, vehicle coverage, and the ability to accurately read transmission data. Don’t hesitate to leverage resources like online forums and reviews to gain insights from other users’ experiences. With the right scan tool, you can effectively monitor and diagnose potential issues with your 47RE transmission.
