Apparatus and Method For Increasing Transmission Line Fluid Pressure

An apparatus for increasing the fluid pressure within a transmission assembly, the transmission assembly including a transmission, a pressure sensor, and a controller, the pressure sensor in fluid communication with the transmission to sense pressure therein and deliver a signal indicative of sensed pressure to the controller, said apparatus consisting essentially of:

• a first part configured and dimensioned to be electrically coupled to said pressure sensor;
• a second part configured and dimensioned to be electrically coupled to the controller;
• a plurality of conductors communicating between said first part and said second part;
• and
• a voltage modifier having a resistance of at least 100 ohms disposed in series with only one of said plurality of conductors.

A method for increasing the pressure of transmission fluid in a transmission, comprising:

• measuring a first pressure of transmission fluid in the transmission;
• generating a first signal indicative of the pressure;
• modifying the first signal to a second signal indicative of a second pressure that is less than the first pressure when the transmission is in use by a vehicle;
• and
• increasing the first pressure based upon the second signal.

A transmission system installed in a vehicle, the transmission system comprising:

• a transmission;
• a pressure sensor in communication with a pressurized fluid residing inside said transmission and generating a first signal indicative of a first pressure of said pressurized fluid in said transmission;
• a pressure booster coupled to said pressure sensor and generating a second signal indicative of a second pressure from said first signal, wherein said second signal, when said transmission is in use by the vehicle, is less than said first signal, and wherein said second signal, when the vehicle is not being operated, is about the same as said first signal;
• and
• a controller in electronic communication with said pressure booster for receiving said second signal.

A pressure booster for electronically increasing the fluid pressure in a transmission system, the transmission system including a pressure sensor configured to generate a first signal indicative of an actual pressure within the system, a controller configured to receive the first signal and generate a second, control signal based thereon, and a valve configured to control fluid pressure in the system based upon the second, control signal received from the controller, the pressure booster comprising:

• at least one member configured and dimensioned to be electronically coupled between the pressure sensor and the controller:
• a plurality of conductors disposed within said at least one member, each said conductor providing electrical communication between corresponding conductors of said pressure sensor and controller;
• and
• a resistor disposed in series with one of said conductors, the resistor having a resistance sufficient modify said first signal received by the controller to be indicative of a pressure lower than actual pressure such that the controller generates a second, control signal indicative of a higher pressure requirement.
