2007.5-2012 6.7L 68RFE Transmission Tuning

Dedicated TCM calibration for the 68RFE six-speed automatic behind the 2007.5–2012 6.7L Cummins. The 68RFE is known for being a weak link at elevated power levels — a proper TCM tune is the first line of defense, tightening shifts and managing torque input to keep the transmission alive.

What's included

• VIN-matched 68RFE TCM calibration
• Increased line pressure, revised shift scheduling, and torque management calibration
• Torque converter lockup strategy tuned for your power level and use case
• Datalogging support
