DIESELR EZ Lynk Transmission Tune File T93 (2020-2023 6.6L L5P Duramax)

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.
