Xtool D7 and D8 scan tools offer Automotive Scan Tool Relearn Capabilities, specifically for performing a transmission fast learn service on a 6T45 Gen 2 transmission. This article explores the capabilities of these tools and clarifies the differences between various models.
Xtool D7 Variants and Transmission Fast Learn
Xtool confirms that the D7 can perform a Transmission Service Fast Learn on a 2014 GMC Terrain with a 2.4L engine and 6T45 transmission. There are several D7 variants available: the D7, D7S, and D7W.
The D7S boasts upgrades over the standard D7, including CAN FD and DoIP protocol compatibility, increased storage (2+64G vs. 2+32G), an 8MP camera, a kickstand, compatibility with the XV100, a new user interface, a larger 5000mAh battery, and a dedicated charging cable. The D7W is identical to the D7S, but offers wireless connectivity.

Choosing Between Xtool D7 and D8 for Transmission Relearn
Both the Xtool D7 and D8 offer the necessary automotive scan tool relearn capabilities for a 6T45 Gen 2 transmission fast learn. The best choice depends on individual needs and budget. The D7 series provides a more affordable option, while the D8 offers advanced features and functionalities for professional use.
Ultimately, either the D7 or D8 provides a solution for performing this critical transmission service. Whether a transmission can independently perform a “learn” procedure without a scan tool during driving remains uncertain. Consult your vehicle’s service manual for specific instructions and recommendations.
