Engine Synchro-Shift ™(ESS)™ System 973177

Meritor Heavy Vehicle Systems in conjunction with Detroit Diesel Corporation has developed an advanced patented shift system. The system monitors input and output speeds of the transmission, the neutral position of the shift lever, and the position of a ‘shift intent’ switch on the shift knob. The electronic controller processes this information and adjusts engine torque and speed to effect a shift of the manual transmission. This feature significantly reduces the driver workload while shifting.
