The ATS Stage 4 Allison LCT1000 Crate Transmission is designed specifically for 6.6L LMM Duramax trucks with 4WD and PTO functionality. Whether you’re towing heavy loads, running performance upgrades, or just want the peace of mind that comes with added strength and durability, this transmission package has you covered.

Complete Transmission Package With Proven ATS Performance
This package is more than just a replacement transmission. It includes ATS’s Five Star torque converter to improve power transfer and help your truck handle increased load demands with ease. A deep transmission pan boosts fluid capacity and cooling, which helps protect internal components when the heat is on. The ATS Co-Pilot Transmission Controller is also included, providing better control over shift timing and pressure for smoother, more reliable performance. Inside the transmission, billet input and output shafts replace factory weak points with heavy-duty components built to withstand higher torque levels. Whether you use your Duramax for work or play, this package is designed to keep you moving forward. Please be aware, a $500 shipping surcharge will apply at checkout.
