Torque Reduction

Engine torque reduction is a computer strategy that has been used in vehicles for many years now. When the selector lever is used to place the transmission into reverse or drive from either park or neutral, a command is given to reduce engine torque. This assists in providing a smooth engagement into gear. Likewise, torque reduction is commanded to take place during each upshift for smooth shifting. This strategy can also be used in vehicles equipped with adaptive cruise control or when traction control becomes activated.
