Fluids for classical automatic transmissions, dual-clutch gearboxes (DCT/DSG), and continuously variable transmissions (CVT)

Automatic transmissions have evolved so dramatically over the past decades that today the same term covers fundamentally different mechanisms. A classical hydromechanical automatic transmission, a continuously variable transmission (CVT), and a dual-clutch robotic gearbox are all referred to as “automatics,” yet each type places its own distinct requirements on the working fluid. One of the […]
