  • Patent number: 6019703
    Abstract: A transmission assembly and method for controlling a torque converter of a transmission assembly in which an electronic controller monitors the load on the vehicle power train in addition to a number of other vehicle dynamics, including the currently engaged gear ratio and the temperature of the transmission fluid. The electronic controller is operable for causing the activation of the converter clutch in response to a number of predetermined operating conditions, one of which includes the operation of the vehicle when the fluid in the torque converter exceeds a predetermined temperature and the vehicle power train is operated under a heavy load for a period of time which exceeds a predetermined time interval. Engagement of the converter clutch during such times inhibits relative rotation between the torque converter turbine and impeller, improving fuel economy and preventing the torque converter from generating a substantial amount of heat.

  • Patent number: 5992481
    Abstract: A filling aid for field filling the engine cooling system of automotive vehicles with cooling liquids. For field service, the filling aid is mounted in a stabilized upright orientation by an integral fluid sealing connection to a filler neck of the deareation chamber of a coolant bottle of the system so that it extends above the bottle. Coolant is added into the cooling system through the filling aid until the filling aid and deareation chamber are filled with coolant. Because a taller column of coolant has been established by use of the filling aid, potential energy is increased and coolant is quickly fed by increased pressure and force into the engine cooling system. When sufficient coolant fills the system, any coolant left in the filling aid may be released by removing a closure clamp previously installed on an overflow tube leading from the deareation chamber so that it drains with no spills from the filling aid to an overflow chamber of the coolant bottle.
