Abstract
The present invention is directed to methods and systems for improving the operation of a transmission for an automotive vehicle, and in particular the transmission as installed by the original automobile manufacturer. The methods and systems of the present invention modify the original hydraulic fluid circuits of the automotive transmission provided by the automobile manufacturer to adjust the feel or firmness of upshifts of the transmission perceived by drivers and occupants of vehicles having the modified transmissions.
Claims20
A method of modifying the hydraulic circuitry of a “factory installed” automotive transmission having an intermediate clutch coupled to a “1-2” shift valve by a first fluid flow passageway, a direct clutch coupled to a “2-3” shift valve by a second fluid flow passageway, and an overdrive clutch coupled to a “3-4” shift valve by a third fluid flow passageway, the steps of said method comprising:
- adjusting the rate of fluid flow through at least one of said first, second or third fluid flow passageways for adjusting the fluid pressure applied to at least one of said intermediate, direct or overdrive clutches.
A method of modifying the hydraulic circuitry of a “factory installed E4OD automatic transmission” having an intermediate clutch coupled to a “1-2” shift valve by a first fluid flow passageway, a direct clutch coupled to a “2-3” shift valve by a second fluid flow passageway, and an overdrive clutch coupled to a “3-4” shift valve by a third fluid flow passageway, the steps of said method comprising:
- adjusting the rate of fluid flow through at least one of said first, second or third fluid flow passageways for adjusting the fluid pressure applied to at least one of said intermediate, direct or overdrive clutches.
A method of modifying the hydraulic circuitry of a “factory installed” automatic transmission having an overdrive cluch accumulator, a direct clutch accumulator, and an intermediate clutch accumulator in fluid communication with each other through fluid flow passageway means, said fluid flow passageway means having an opening for providing a controlled leak of fluid therefrom, the steps of said method comprising:
- blocking the leak in said fluid flow passageway means.
