MOTUL AUTOMATIC TRANSMISSION CLEAN is a pre-drain automatic transmission cleaner designed to be used in all types of automatic transmissions including a conventional system with torque converters (AT), a dual clutch transmission (DCT) or a continuously variable transmission (CVT) in preparation for an oil change. Effectively cleans deposits, sludge and varnish on the automatic transmission components. These contaminants are then drained with the old transmission fluid. MOTUL AUTOMATIC TRANSMISSION CLEAN is highly effective and compatible with all seals, joints,  O-rings and mechanical components. Helps to increase the life of your vehicle's transmission system.
