Precision Components Calibrated For Power Towing And Longevity

The ATS 309-864-4248 Stage 6 Allison LCT1000 Crate Transmission is purpose-built for 2001–2002 6.6L Duramax LB7 4WD trucks requiring upgraded drivetrain reliability. The transmission includes billet input, output, and intermediate shafts to prevent twisting under load, along with a billet P2 carrier and C2 hub for superior rotational strength. A modified P1 sun gear reinforces the gearset’s ability to withstand high torque environments. The included ATS Five Star Torque Converter improves torque multiplication while maintaining lock-up precision, making it ideal for both performance acceleration and towing applications. With the deep transmission pan, fluid capacity is increased for improved thermal control during prolonged strain. The ATS Co-Pilot Transmission Controller monitors driver input and adjusts shift strategy and line pressure on the fly to maintain safe and responsive shifting. This complete system ships as a crate unit, ready for installation with all core performance upgrades included. A $500 shipping surcharge applies due to the size and freight requirements of this heavy-duty assembly.
