2022-2024 Cummins AMDP 68RFE EZ-Lynk TCM Tune File

Note: this is an add-on service. It requires an active AMDP ECM support package on the same truck (a 4-Week Lynk package still inside its 4 week window, or a Lifetime Lynk package), such as our 2022-2024 Cummins AMDP EZ-Lynk Support Pack. The ECM and TCM flash together in the same file, so 68RFE transmission tuning cannot be purchased on its own.

Add AMDP custom 68RFE transmission tuning to your 2022-2024 Ram 2500 or 3500 with the 6.7L Cummins, delivered over the cloud to your EZ-Lynk Auto Agent 3. AMDP recalibrates the 68RFE so it shifts, holds and locks up the way your AMDP tuned Cummins needs it to.

Package options:

• 68RFE Transmission Tuning: adds 68RFE tuning to your existing AMDP support package.
• Lifetime Lynk Upgrade + 68RFE Transmission Tuning: upgrades a 4-Week Lynk package to Lifetime Lynk support and adds 68RFE tuning.

• Increased line pressure gives the clutch packs a more secure hold for firm, controlled engagement, less slip and longer transmission life.
• Optimized shift points keep the truck in its power band and prevent lugging.
• Raised shift points available as an option if you want the truck to hold gears longer and pull harder before shifting.
• Converter lockup strategy adjusted for your tuned truck.
• Firmer shifts with adjusted shift firmness and timing for faster, more positive gear changes.
• Better drivability under load, whether you are daily driving, towing heavy or running higher power levels.
• Calibrated by AMDP for the 68RFE behind the 2022-2024 6.7L Cummins and sent straight to your Auto Agent through the EZ-Lynk app.

• An EZ-Lynk Auto Agent 3 is required to load the tuning and is not included.
• Requires an active AMDP ECM support package on the same truck (4-Week Lynk within its 4 week window, or Lifetime Lynk).
• For 2022-2024 Ram 2500 and 3500 pickups with the 68RFE transmission only. Ram 3500 cab and chassis trucks use the AISIN transmission, not the 68RFE. For those trucks, see the 2013-2024 Cummins AMDP AISIN EZ-Lynk TCM Tune File.
