Automatic Transmissions

Automatic transmissions in Cummins systems shift gears without driver input. Hydraulic systems control clutch engagement and gear changes. Torque converters multiply engine torque during acceleration. Planetary gearsets provide multiple speed ratios. Electronic controls optimize shift timing for performance and fuel economy. Heavy-duty components withstand high torque and heat. Cummins pairs automatic transmissions to engine output for reliability and smooth operation.
