DIESELR EZ Lynk Transmission Tune File (2019-2024 6.7L Cummins *AISIN ONLY*)

The DIESELR EZ Lynk Transmission Tune File (2019–2024 Cummins 6.7L AISIN) is built to bring your transmission in line with the added power from engine tuning. Stock AISIN programming often feels sluggish, with short-shifting and low-RPM lugging that hold your truck back. This calibration solves those issues, giving you stronger, more predictable performance in every driving scenario.

With adjusted shift points, improved torque management, and refined response, this tune makes your Cummins AISIN feel sharper, smoother, and more controlled. Acceleration is more powerful, towing is more stable, and gear changes happen exactly when you need them. It’s the missing piece for owners running ECM tunes, larger turbos, bigger tires, or heavy towing setups.

Included:

• AISIN transmission tune file (4-week Lynk access)
• Upgrade available for lifetime access – Part #DSLRT-500130

Requirements:

• EZ Lynk Auto Agent 3

Key Features:

• Eliminates 1000 RPM lugging issues common in Dodge AISIN trucks

DIESELR transmission tunes are dyno-tested, proven in real trucks, and supported by the most knowledgeable tuning team in the industry. From install to fine-tuning, you get real tech support — not call centers — so your truck runs the way it should.
