Big Power and Heavy Loads Demand a Stronger Transmission

If you’ve built your 2006-2007 Silverado or Sierra 2WD Duramax for more than just daily driving, you already know the stock Allison can become a weak link. Whether you’re hauling equipment, towing long distance, or squeezing out every bit of power from your LBZ, LLY, or LMM engine, you need a transmission that can keep up. That’s where the ATS Stage 4 Allison LCT1000 Crate Transmission comes in. This package is built to handle the kind of real-world stress that stock components can’t. It arrives fully assembled and ready to install, giving you the peace of mind to get back on the road or back to work without hesitation.

Complete ATS Performance From the Inside Out

The strength of this package comes from the proven combination of ATS performance upgrades. It starts with the Five Star torque converter, which helps your truck respond better under load by improving power delivery and efficiency. The deep transmission pan increases fluid capacity, helping to reduce heat and extend the life of your transmission when the going gets tough. With the ATS Co-Pilot Transmission Controller on board, you’ll experience smoother, more controlled shifts no matter what you’re towing or hauling. Inside, billet input and intermediate shafts replace factory parts known to fail when power levels rise, giving your drivetrain the durability to handle whatever you throw at it. Just keep in mind, a $500 shipping surcharge will apply at checkout.
