Proven Power Handling for Towing and Performance Builds

When your Duramax-powered truck starts working beyond stock limits—whether towing heavy loads or running higher horsepower—you need a transmission that won’t let you down. The ATS 309-835-4332 Stage 3 Allison LCT1000 Crate Transmission is designed to give your 4WD, PTO-equipped truck the strength and control it needs. This package includes ATS’s performance-built Allison LCT1000 transmission, their Five Star torque converter for efficient torque transfer, and a deep transmission pan that boosts fluid capacity to help reduce heat during demanding use. Whether you’re hauling equipment, towing a trailer cross-country, or pushing extra power with a tune, this complete package helps you put that power to work with confidence.

Built for Long-Term Durability and Smarter Control

ATS doesn’t stop at stronger hardware. They also include their Co-Pilot Transmission Controller, giving you enhanced control over shift timing and torque converter lock-up to improve drivability and reduce unnecessary wear. The billet input shaft adds another layer of durability, making sure the transmission can handle higher torque without risking failure. Everything is designed to work together, making this package ideal for serious work trucks or performance builds. ATS also makes the shipping process simple with a $500 flat rate round-trip charge. If you’re looking for a transmission upgrade that’s ready for real-world abuse, this Stage 3 package checks all the right boxes.
