摘要： A method for controlling a coast down downshift that is produced in an automatic transmission by disengaging an off-going control element and engaging an oncoming control element, including the steps of determining a first desired pressure magnitude of the off-going control element and a first desired pressure magnitude of the oncoming control element, executing the current downshift using said first desired pressure magnitudes, determining during execution of the current downshift corrections of said first desired pressure magnitudes that occur during the current downshift, determining a second desired pressure magnitude of the off-going control element and a second desired pressure magnitude of the oncoming control element, using said corrections and the second desired pressure magnitude to determine a subsequent desired pressure magnitude of the off-going control element and a subsequent desired pressure magnitude of the oncoming control element, and executing a downshift using said subsequent desired pressure magnitudes.

摘要： A method for controlling a torque converter clutch in an automatic transmission of a vehicle that includes an engine, an accelerator pedal and wheels, the converter clutch alternately connecting and disconnecting the engine and transmission when the clutch is engaged and disengaged. The method includes determining that the vehicle is either ascending a grade or operating in a loaded condition, determining that the clutch is engaged, determining whether the vehicle is operating in a curve, preventing disengagement of the clutch if the vehicle is either ascending a grade or operating in a loaded condition and the vehicle is operating in a curve, and allowing disengagement of the clutch if the vehicle is neither ascending a grade nor operating in a loaded condition.
