2011-2016 LML Allison 1000 Transmission Tuning

Standalone Allison 1000 transmission calibration for the 2011–2016 LML 6.6L Duramax — built to handle the increased torque output that comes with a performance engine tune.

What's included

• Custom VIN-matched Allison 1000 TCM calibration
• Shift pressure and shift timing tuning for firm, consistent engagement
• Torque converter lockup calibration to reduce slippage and heat under load

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 LML engine calibration.

All calibrations are developed for emissions-compliant performance and must be used in accordance with applicable local, state, and federal regulations.
