At any time, one or more stream licenses may be added to a FlashScan V2 device. Stream licenses allow unlimited tuning for specific controllers, in this case the GM A40 Allison 6 Speed Transmission controller.
Note: During 2009 GM changed the TCM controller used by the 2009 Allison 6 Speed transmission. Currently the A40 TCM is supported by this product, but the A42 is not.
The GM Transmission Supported Vehicles list provides a comprehensive summary of the vehicles covered by this stream.
There is no requirement to return your FlashScan hardware to EFILive. Stream Licenses are delivered via email during regular New Zealand business hours.
Previous purchase of FlashScan V2 with GM Tuning is required for this product.
Customers who purchase the A40 Stream License for Allison 6 Speed Transmissions should consider purchasing the matching E35 LBZ/LMM Duramax Engine Stream License.
Enter your FlashScan V2 Serial Number in the box on the left.
