Standalone Allison 1000 transmission calibration for the 2004.5–2007 LLY/LBZ 6.6L Duramax — firm, controlled shifts calibrated to handle elevated engine output.
What's included
- Custom VIN-matched Allison 1000 TCM calibration
- Shift pressure and shift point optimization
- Torque converter lockup calibration for better drivetrain efficiency
How it works
Files are delivered via EFI Live FlashScan V2. The calibration is built from your stock TCM file and locked to your VIN. A FlashScan V2 device is required to flash the TCM.
Support tiers
- Limited (4 Weeks): Four weeks of revision rounds; tune stays on your tool after the window closes.
- Full (Lifetime): Unlimited revisions and lifetime access.
Requires an EFI Live FlashScan V2 device. Transmission tune only — does not include LLY/LBZ engine calibration.
Calibrations are developed for motorsport and off-road use. Verify local regulations before use on public roads.
