Designed for Real Work and Reliable Performance

If your 2004.5–2005 Silverado or Sierra 2500HD/3500HD with the 6.6L LLY Duramax is still running its factory transmission, you may be limiting the true potential of your truck. The ATS Stage 2 Allison LCT1000 Crate Transmission Package is the upgrade built for owners who tow, haul, or run additional power and need their drivetrain to keep up. This complete package is specifically designed for 2WD PTO-equipped models and includes ATS’s fully built performance transmission, a Five Star torque converter to improve power delivery, and a deep transmission pan that boosts fluid capacity and helps manage heat. Together, these upgrades give your truck the durability and drivability needed for serious use.

Complete Control with Co-Pilot Technology

Rounding out the package is the ATS Co-Pilot Transmission Controller. This system gives you more precise control over shift timing and torque converter lock-up, helping your truck shift smoother, run cooler, and handle higher torque loads with confidence. Whether you’re using your Duramax for work or play, this package ensures your transmission is ready to perform without hesitation. Installation is designed to be straightforward, making it a great bolt-in solution for drivers who expect more from their drivetrain. Just remember to account for the $500 freight shipping charge that will be added at checkout. This is an investment that pays off in long-term reliability and performance.
