Fully Loaded With ATS Performance Upgrades

This isn’t just a rebuild—it’s a complete performance package featuring ATS’s most trusted components. The Five Star torque converter improves torque multiplication, helping your truck pull harder and drive smoother, even under heavy load. The deep transmission pan increases fluid capacity, keeping things cooler and extending transmission life during tough conditions. You also get the ATS Co-Pilot Transmission Controller, which optimizes shift timing and line pressure for improved drivability and better control. Inside, billet input and intermediate shafts replace factory parts that are prone to failure when power levels rise. This package is designed to give your Duramax the durability it needs to keep working for years to come. Please note, a $500 shipping surcharge will be applied at checkout.
