Description
Description
The DIESELR EZ Lynk Transmission Tune File T93 (2020–2023 L5P Duramax 6.6L) is built for drivers who want more from their truck than the stock TCM can deliver. If your engine is tuned but your transmission is still running factory mapping, you’re holding back performance. This custom-calibrated file is designed to bring out the full capability of your 10-speed transmission, making every shift count.
With the T93 module unlocked, this tune file improves shift timing, torque management, and converter lockup. The result is crisper shifts under throttle, reduced gear hunting, and more controlled power delivery when towing heavy loads. Whether you’re hauling equipment, pulling a trailer, or daily driving, this tune file ensures your transmission keeps up with your engine tuning.
Requirements
- Unlocked T93 TCM (must be unlocked before flashing)
- EZ Lynk Device with AutoAgent software
- Works in combination with DIESELR engine tuning
Key Features
- Matched to DIESELR engine files for seamless operation
- Smoother, faster shifts under load and at wide-open throttle
- Optimized torque management and towing manners
- Improved throttle feel with reduced delay
- Safe, proven calibration process tested on real trucks
When paired with DIESELR’s engine tuning, the EZ Lynk T93 Transmission Tune File delivers the balanced performance and long-term reliability serious Duramax owners demand.
