2019-2024 6.7L Cummins High Output Aisin Transmission TCM Tuning

The Aisin equipped 2019-2024 Ram 2500/3500 High Output is known for its towing performance. However, there are many complaints when it comes to shift quality and timing. Many customers gripe about the time between shifts and dramatic de-fuel, along with the underwhelming sense of power that the stock TCM tuning conveys.

Calibrated Power's Custom TCM tuning decreases the time between shifts and improves the clutch holding capacity by electronically increasing line pressure. This will make a more durable, better shifting, and better driving transmission. It can also help keep the engine in the ideal RPM range to utilize all of its potential power and added efficiency.

Why do you need TCM Tuning?

• Works with any ECM Tuning to provide smooth shifting and superior driveability
• Torque converter lockup strategy helps put power to the ground when you need it most
• Improves clutch holding capacity with increased line pressure
