2011-2012 F250-F450 6R140 Transmission Tuning (ezlynk)

Standalone 6R140 TorqShift transmission tuning for the 2011–2012 Ford F-250 through F-450 6.7L Power Stroke. Designed as a transmission-only add-on if you already hold the matching engine package, or as an upgrade to protect your drivetrain from increased power.

What's included

• Custom TCM calibration targeting shift firmness, converter clutch apply, and line pressure curves
• Tuned shift scheduling optimized for performance and towing duty cycles
• Datalogging parameters for transmission temperature and shift quality monitoring via ezlynk

How it works

Tune files are pushed to your ezlynk AutoAgent 3 device over Wi-Fi. The AutoAgent handles both ECM and TCM flash in sequence. Assumes you have an ezlynk AutoAgent 3 already in use or ordered alongside your engine tune.

Support tiers

• Limited — 4 Weeks: Revision window closes after four weeks; files remain on the tool permanently.
• Full — Lifetime: Unlimited revisions with no expiration.

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