Upgrade Your Transmission Before Power Leaves You Behind

When your LMM Duramax is built to haul, race, or just leave stock trucks in the dust, your transmission can’t be the weak link. The ATS Stage 6 Allison LCT1000 Crate Transmission is the kind of upgrade that lets your 2007.5–2010 Duramax actually use the power you’ve worked so hard to build.

Whether you're daily driving a modified truck or hitting the strip on the weekends, this setup gives you the strength and confidence to push harder without hesitation. The included Co-Pilot transmission controller fine-tunes your shifting and pressure adjustments on the fly, so your truck always feels dialed in no matter the load or terrain. If you're tired of babying your transmission every time you hammer the throttle, this is the solution that keeps you in control. It’s all about putting power to the pavement without compromise.

Reinforced Internals Calibrated For Consistent High Output Performance

The ATS Stage 6 Allison LCT1000 Transmission for 2007.5–2010 6.6L LMM Duramax 4WD trucks is engineered for strength, stability, and shift precision under high-stress conditions. This system is equipped with billet input, output, and intermediate shafts that eliminate the flex and failure points found in stock setups. Paired with a billet P2 carrier, C2 hub, and a modified P1 sun gear, this transmission can comfortably handle the torque output of heavily modified diesel builds. The Five Star torque converter provides improved lock-up and efficient power transfer, while the deep transmission pan increases cooling capacity and fluid life. The ATS Co-Pilot Transmission Controller actively monitors load and adjusts line pressure and shift timing in real time to prevent clutch slippage and heat buildup. This complete crate transmission is built for those demanding more from their drivetrain, whether it's towing at the limit or pushing for personal bests at the track. A $500 shipping surcharge applies due to the size and weight of this heavy-duty unit.
