The gearbox in the dodge charger transmission is designed to manage high torque outputs, particularly in performance trims such as the R/T, Scat Pack, and SRT Hellcat. These cars are equipped with heavy-duty variants of the 8-speed automatic or specialised performance transmissions built to handle the power of engines producing more than 700 horsepower. Routine maintenance, such as fluid changes and inspections, is critical to extending the life and reliability of these systems.
