For automotive repair professionals and DIY enthusiasts working with modern vehicles, having the right diagnostic tools is essential. When it comes to transmission service, specifically for the 6T45 Gen 2 transmission found in many General Motors vehicles, an Obd2 Transmission Scanner capable of performing a “Transmission Service Fast Learn” procedure is invaluable. This article focuses on the Xtool D series scan tools, including the D7, D7S, D7W, and D8 models, and their capabilities for this specific transmission service.
The original manufacturer, Xtool, has confirmed that several of their popular scan tools within the D series are equipped to handle the “Transmission Service Fast Learn” function on 2014 GMC Terrain models with the 2.4L engine and 6T45 transmission. This is a critical function after performing transmission repairs or fluid changes, as it allows the transmission control module (TCM) to quickly and efficiently learn new operating parameters, ensuring smooth shifting and optimal transmission performance.
Among the confirmed compatible models are the Xtool D7, D7S, D7W, and D8. While all these models can perform the essential “Transmission Service Fast Learn,” there are differences between them that may influence a user’s choice depending on their specific needs and budget.
The Xtool D7S and D7W are presented as upgraded versions of the base D7 model. Key improvements in the D7S over the D7 include:
- Expanded Protocol Support: D7S supports CAN FD and DoIP protocols, while D7 only supports CAN FD. This broader compatibility makes the D7S more future-proof for newer vehicle models.
- Increased Storage: The D7S boasts 2+64G of storage compared to the D7’s 2+32G, allowing for more data logging and software updates.
- Enhanced Camera: D7S features an 8MP read camera, a feature not available on the D7.
- Practical Design: D7S includes a kickstand for easier hands-free operation, which the D7 lacks.
- Accessory Compatibility: D7S is compatible with the XV100 video scope, expanding its diagnostic capabilities, while D7 is not.
- Updated User Interface: D7S utilizes a newer user interface, potentially offering a more streamlined and user-friendly experience compared to the older UI on the D7.
- Improved Battery Life: D7S has a larger 5000mAh battery compared to the D7’s 4000mAh, providing longer operating time.
- Charging Convenience: D7S includes a dedicated charging cable, while D7 uses a standard USB cable for charging.
The Xtool D7W distinguishes itself from the D7S primarily by offering wireless connectivity, whereas the D7S is wired. This wireless capability can provide added convenience and flexibility in a workshop environment.
Moving up the range, the Xtool D8 is positioned as a more advanced tool compared to the D7 series. While also capable of “Transmission Service Fast Learn,” the D8 offers several hardware and software advantages:
- Superior Hardware: The D8 features enhanced hardware specifications, including a larger screen and battery, contributing to a better user experience and durability.
- Direct CAN FD Support: Like the D7S and D7W, the D8 supports CAN FD protocol vehicles directly.
- Advanced Software Functions: D8 includes ECU Configuration, ADAS (Advanced Driver-Assistance Systems) capabilities, and PMI (Programmable Module Installation), features not available in the D7. These functions cater to more complex diagnostic and programming tasks.
- Add-on Compatibility: D8 is compatible with add-ons like digital inspection cameras, further expanding its utility.
- Enhanced Key Programming: D8 can work with key programmers like KC-100 and KC-501, significantly extending its IMMO (Immobilizer) and key programming capabilities beyond the D7.
- More Special Functions: D8 offers 38 commonly used special functions compared to the D7’s 36, providing a broader range of diagnostic and service procedures.

In conclusion, for technicians seeking an OBD2 transmission scanner to perform “Transmission Service Fast Learn” on 6T45 Gen 2 transmissions, the Xtool D series offers several viable options. The D7, D7S, D7W, and D8 are all confirmed to support this function. The choice between these models will depend on individual needs, budget, and desired features beyond basic transmission service. For users needing advanced functionalities, broader vehicle compatibility, and enhanced hardware, the D8 and D7S/D7W variants offer significant upgrades over the base D7 model. However, for solely focusing on transmission fast learn and basic diagnostics, the Xtool D7 remains a capable and cost-effective solution.
