A Serious Upgrade for Hardworking and High-Horsepower LB7 Duramax Trucks
If you’re pushing the limits of your 2001-2002 LB7 Duramax, the factory transmission might not be able to keep up for long. That’s where the ATS 309-854-4248 Stage 5 Allison LCT1000 Crate Transmission comes in. Designed specifically for 4WD Silverado and Sierra 2500HD and 3500HD models, this complete package delivers the durability and performance your truck needs for heavy towing, daily driving, or high-horsepower builds. This system includes ATS’s performance-built LCT1000 transmission, paired with their Five Star torque converter to improve power transfer and reduce slippage under load. A deep transmission pan is also included to help control fluid temperatures during hard use, while the ATS Co-Pilot transmission controller fine-tunes shift quality and line pressure for smooth, reliable performance.
Billet-Strength Components for Maximum Durability
This Stage 5 package takes durability to the next level with billet input, output, and intermediate shafts, giving you the strength needed to handle extreme torque levels without worrying about failure. Whether you’ve upgraded your turbo, added tuning, or just need the confidence to haul heavy loads without holding back, this transmission is built to handle it all. It’s a direct bolt-in replacement, making installation simple with no extra modifications required. With ATS engineering this complete system to work together, you get a drivetrain upgrade you can trust for years to come.
