Standalone Allison 10L1000 (10-speed) transmission calibration for the 2017–2023 L5P 6.6L Duramax, delivered via EZLynk AutoAgent 3 — for owners who already have an L5P engine tune and want the automatic to keep pace.

What's included

• Custom VIN-matched Allison 10L1000 TCM calibration
• Shift pressure, shift timing, and torque converter lockup tuning for the 10-speed unit
• Calibration built to handle elevated engine torque without excessive clutch wear

How it works

Files are delivered via EZLynk AutoAgent 3. The calibration is built from your stock TCM file and VIN-locked. An EZLynk AutoAgent 3 device is required to load the tune onto the TCM.

Transmission tune only — does not include L5P engine calibration. Requires an EZLynk AutoAgent 3 device. Not compatible with EFI Live or other platforms.

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