Transmission Tuning for T93
If you're running a L5P with a T93 transmission controller, factory shift logic can feel soft or hesitant under load, especially when towing or accelerating hard. AMDP's tailored transmission calibration fine-tunes shift timing, torque control, and line pressure so every gear change feels tighter and more decisive, with noticeably better response when you're pushing the truck under heavy loads. The whole process runs through your EZ Lynk AutoAgent device via the OBD port. No extra hardware, no disassembly, just plug in and flash.
Optional TCM Tuning Available.
Tune File Installation Guide
  1. Purchase this support package for the required tuning period. After your purchase is completed, we will prepare your custom tune file and notify you once the file is ready in the cloud.
  2. Before flashing the tune, fill the DEF tank and perform a DEF level reset if you have access to a professional scan tool. We recommend clearing any DEF-related warnings from the dashboard before the tuning process begins. However, if the warning cannot be cleared beforehand, our tuning support team can assist with the next steps after the flash is completed.
  3. An AutoLink connection request from AMDP Custom Tuning will appear on your EZ LYNK app. Select "Accept" to authorize the connection.
  4. Select the tune file folder that corresponds with the model year displayed by EZ LYNK, then flash the desired calibration file to your vehicle.
