2007.5-2010 LMM Allison 1000 Transmission Tuning

Standalone Allison 1000 transmission calibration for the 2007.5–2010 LMM 6.6L Duramax — firm, precise shifts tuned to hold up under increased engine load.

What's included

• Custom VIN-matched Allison 1000 TCM calibration
• Shift pressure and shift point tuning for aggressive and everyday driving
• Torque converter lockup optimization for reduced heat and drivetrain loss

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 LMM engine calibration.

Calibrations are developed for motorsport and off-road use. Verify local regulations before use on public roads.
