Overview

You've already invested in ECM tuning, so don’t leave the rest of your truck’s performance on the table. The Transmission Tune from DuramaxTuner.com is designed to bring out the full potential of your LML by giving your 6-speed Allison the shift strategy it was always missing. This upgrade improves shift quality, makes the truck feel more responsive, and helps keep your power to the ground right when you need it. Whether you're towing up a steep grade or just cruising to work, the difference in how your truck shifts is instantly noticeable. No more soft or sluggish gear changes, just firm, confident shifts that keep your driving experience smooth and strong. Best of all, it uses your existing EFI Live SPADE hardware, so you’re not buying more gear or extra licenses to get started. If you want to make the most of your tuning and truly enjoy how your truck drives, this transmission tune is a no-brainer.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
