Xtool D7 and D8 scan tools offer Transmission Service Fast Learn functionality for GM vehicles, including the 6T45 Gen 2 transmission. This article explores the capabilities of these tools and highlights the key differences between various models.
Xtool D7 for GM Transmission Relearn
Confirmed by Xtool, the D7 can perform Transmission Service Fast Learn on vehicles like a 2014 GMC Terrain with a 2.4L engine and 6T45 transmission. Several D7 variants exist, each with unique features:
- D7: Base model with CAN FD protocol support, 2+32GB storage, and a 4000mAh battery.
- D7S: Upgraded version with CAN FD and DoIP protocols, 2+64GB storage, an 8MP camera, a kickstand, XV100 compatibility, a new user interface, and a 5000mAh battery with a dedicated charging cable.
- D7W: Wireless version of the D7S, offering the same functionality without the need for a physical connection.
The core functionality, including Transmission Service Fast Learn, remains consistent across all D7 models. The differences primarily lie in hardware and user experience enhancements.
Xtool D8: Enhanced Features for GM Vehicles
The Xtool D8 also provides Transmission Service Fast Learn for GM vehicles. It boasts superior hardware compared to the D7, including a larger screen and improved battery life.
Key advantages of the D8 include:
-
Direct CAN FD Compatibility: Unlike the D7, the D8 directly supports CAN FD protocol vehicles.
-
Advanced Functionality: The D8 offers ECU Configuration, ADAS, and PMI functionalities not available on the D7.
-
Expandability: The D8 supports add-ons like digital inspection cameras and key programmers such as the KC-100 and KC-501, extending its capabilities beyond diagnostics.
-
Comprehensive Special Functions: The D8 includes 38 commonly used special functions compared to the D7’s 36.
The D8 represents a more comprehensive solution for professionals seeking advanced features and expandability.
Choosing the Best GM Scan Tool for Your Needs
Both the Xtool D7 and D8 offer Transmission Service Fast Learn capabilities for GM vehicles. The best choice depends on individual needs and budget. The D7 provides a cost-effective solution for essential relearn procedures, while the D8 offers a more comprehensive and expandable platform for advanced diagnostics and programming. Whether a transmission can perform a self-learn procedure without a scanner remains unclear and likely varies depending on the specific vehicle and transmission. Using a dedicated scan tool ensures a proper and efficient relearn process.
