2013-2018 6.7L 68RFE / Aisin Transmission Tuning

Dedicated TCM calibration for the 68RFE six-speed or Aisin AS69RC automatic transmission behind the 2013–2018 6.7L Cummins. Specify your transmission at checkout. Both units benefit from custom calibration when paired with an engine tune — shifts become crisper and the transmission better manages the torque load.

What's included

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