The Five Star torque converter boosts low-end torque and improves throttle response, making everyday driving feel more responsive and controlled. You’ll also notice smoother gear shifts and better clutch engagement thanks to the Co-Pilot Transmission Controller, which optimizes shift timing under load. Whether you’re hauling equipment, pulling a trailer up a steep grade, or just want more confidence under your right foot, this transmission package keeps the power flowing. It’s not just a replacement, it’s a serious performance upgrade for diesel owners who expect more from their truck.

The Transmission Built To Handle Serious Power

Under the surface, the ATS Stage 4 Allison LCT1000 is packed with performance-driven components built to take abuse. The billet input and intermediate shafts are engineered to resist twisting and shearing under high torque, making them ideal for trucks that see heavy towing or added horsepower. Its deep transmission pan not only increases fluid capacity but also improves cooling, which helps reduce transmission temperatures during long hauls or aggressive driving. The included ATS Five Star torque converter is a multi-disc unit that enhances torque multiplication while maintaining efficient lockup performance. Paired with the ATS Co-Pilot Transmission Controller, this setup ensures consistent line pressure and shift quality whether you're empty or fully loaded. Built for 2WD models with a PTO provision, this transmission is ready for work applications that demand durability and consistent output. Everything in this package has been fine-tuned for the LB7 Duramax platform from 2003 to early 2004, giving you a direct-fit solution with serious upgrades inside. It's a fully built transmission system you can count on when factory parts just don’t cut it anymore.
