DIESELR EZ Lynk Transmission Tune File – T93 (2020-2023 6.6L L5P Duramax)
Couldn't load pickup availability
DIESELR EZ Lynk Transmission Tune File – T93 (2020–2023 L5P Duramax 6.6L) is designed for trucks where engine output has already exceeded factory transmission behavior. When engine tuning is added without recalibrating the transmission, shift logic, torque control, and drivability are compromised upstream.
This file directly unlocks and calibrates the factory T93 TCM through EZ Lynk. No separate unlock service or additional hardware is required. Shift logic, torque management, and converter behavior are recalibrated to operate correctly with increased power and real-world load conditions.
The result is controlled, deliberate shifting under throttle, reduced gear hunting when towing, and predictable power transfer across all driving scenarios. The transmission behaves as a matched system, not a limiting factor.
Factory T93 TCM Unlock Now Included
This transmission tune file now unlocks and calibrates the factory T93 TCM directly through EZ Lynk. No third-party unlock service. No additional hardware. One controlled process.
Requirements
- EZ Lynk AutoAgent device
- 2020–2023 L5P Duramax equipped with factory T93 TCM
- Designed to operate alongside DIESELR engine ECM tuning
Key Features
- Direct unlock and calibration of the factory T93 TCM
- Matched to DIESELR engine files for cohesive power delivery
- Controlled shifts under load and wide-open throttle
- Refined torque management for towing and work use
- Improved throttle response with reduced delay and hunting
- Proven calibration strategy validated on real-world trucks
When paired with DIESELR engine tuning, the EZ Lynk T93 Transmission Tune File delivers consistent shift behavior, controlled torque transfer, and long-term drivability that factory calibration cannot support once power is increased.
