Dedicated TCM calibration for the 68RFE six-speed or Aisin AS69RC automatic transmission behind the 2019–2026 6.7L Cummins. Specify your transmission at checkout. A transmission tune is especially important on higher-power builds where stock shift pressure and scheduling leave performance and durability on the table.

What's included

• VIN-matched TCM calibration for 68RFE or Aisin AS69RC
• Increased line pressure, revised shift scheduling, and torque converter lockup tuned for your power level
• Transmission-specific torque management calibration
• Datalogging support

How it works

Delivered via EFI Live (FlashScan V2). Submit your VIN and stock TCM file; NanoTorque returns a custom calibration you flash yourself. A FlashScan V2 device is required and not included. 2018+ trucks require an SGW (Security Gateway) bypass cable prior to flashing — not included, must be sourced separately.

Support tiers

• Limited (4 Weeks): Revision window open for four weeks; tune stays loaded on your tool afterward.
• Full (Lifetime): Unlimited revisions and lifetime access.
