Driveability and Transmission improvements are also included with this software release. These changes consist of the following: ? Enhanced clutch protection for more robust torque management during repeated fore and aft movement \(rocking vehicle\). All engines. ? A revised torque convertor lockup schedule that will reduce transmission temperatures in Tow/Cruise mode. All models equipped with RFE transmission. ?
