Automatic Transmissions

Choate Engineering builds automatic transmissions for the 5.9L Cummins to handle high torque and hard use. Each unit shifts smoothly under load and holds power without slipping. Strong internals resist wear from heat and heavy towing. Precision assembly keeps everything aligned and running tight. Choate’s automatics deliver solid performance for daily driving and performance builds.
